<p>Below is a sample homeserver configuration file. The homeserver configuration file
can be tweaked to change the behaviour of your homeserver. A restart of the server is
generally required to apply any changes made to this file.</p>
<p>Note that the contents below are <em>not</em> intended to be copied and used as the basis for
a real homeserver.yaml. Instead, if you are starting from scratch, please generate
a fresh config using Synapse by following the instructions in
<a href="../../setup/installation.html">Installation</a>.</p>
<pre><code class="language-yaml"># This file is maintained as an up-to-date snapshot of the default
# homeserver.yaml configuration generated by Synapse.
#
# It is intended to act as a reference for the default configuration,
# helping admins keep track of new options and other changes, and compare
# their configs with the current default. As such, many of the actual
# config values shown are placeholders.
#
# It is *not* intended to be copied and used as the basis for a real
# homeserver.yaml. Instead, if you are starting from scratch, please generate
# a fresh config using Synapse by following the instructions in
# https://matrix-org.github.io/synapse/latest/setup/installation.html.
# Configuration options that take a time period can be set using a number
# followed by a letter. Letters have the following meanings:
# s = second
# m = minute
# h = hour
# d = day
# w = week
# y = year
# For example, setting redaction_retention_period: 5m would remove redacted
# messages from the database after 5 minutes, rather than 5 months.
################################################################################
# Configuration file for Synapse.
#
# This is a YAML file: see [1] for a quick introduction. Note in particular
# that *indentation is important*: all the elements of a list or dictionary
# should have the same indentation.
#
# [1] https://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html
## Modules ##
# Server admins can expand Synapse's functionality with external modules.
#
# See https://matrix-org.github.io/synapse/latest/modules/index.html for more
# documentation on how to configure or create custom modules for Synapse.
#
modules:
#- module: my_super_module.MySuperClass
# config:
# do_thing: true
#- module: my_other_super_module.SomeClass
# config: {}
## Server ##
# The public-facing domain of the server
#
# The server_name name will appear at the end of usernames and room addresses
# created on this server. For example if the server_name was example.com,
# usernames on this server would be in the format @user:example.com
#
# In most cases you should avoid using a matrix specific subdomain such as
# matrix.example.com or synapse.example.com as the server_name for the same
# reasons you wouldn't use user@email.example.com as your email address.
# See https://matrix-org.github.io/synapse/latest/delegate.html
# for information on how to host Synapse on a subdomain while preserving
# a clean server_name.
#
# The server_name cannot be changed later so it is important to
# configure this correctly before you start Synapse. It should be all
# lowercase and may contain an explicit port.
# Examples: matrix.org, localhost:8080
#
server_name: &quot;SERVERNAME&quot;
# When running as a daemon, the file to store the pid in
#
pid_file: DATADIR/homeserver.pid
# The absolute URL to the web client which / will redirect to.
#
#web_client_location: https://riot.example.com/
# The public-facing base URL that clients use to access this Homeserver (not
# including _matrix/...). This is the same URL a user might enter into the
# 'Custom Homeserver URL' field on their client. If you use Synapse with a
# reverse proxy, this should be the URL to reach Synapse via the proxy.
# Otherwise, it should be the URL to reach Synapse's client HTTP listener (see
# 'listeners' below).
#
# Defaults to 'https://&lt;server_name&gt;/'.
#
#public_baseurl: https://example.com/
# Uncomment the following to tell other servers to send federation traffic on
# port 443.
#
# By default, other servers will try to reach our server on port 8448, which can
# be inconvenient in some environments.
#
# Provided 'https://&lt;server_name&gt;/' on port 443 is routed to Synapse, this
# option configures Synapse to serve a file at
# 'https://&lt;server_name&gt;/.well-known/matrix/server'. This will tell other
# servers to send traffic to port 443 instead.
#
# See https://matrix-org.github.io/synapse/latest/delegate.html for more
# information.
#
# Defaults to 'false'.
#
#serve_server_wellknown: true
# Set the soft limit on the number of file descriptors synapse can use
# Zero is used to indicate synapse should set the soft limit to the
# hard limit.
#
#soft_file_limit: 0
# Presence tracking allows users to see the state (e.g online/offline)
# of other local and remote users.
#
presence:
# Uncomment to disable presence tracking on this homeserver. This option
# replaces the previous top-level 'use_presence' option.
#
#enabled: false
# Whether to require authentication to retrieve profile data (avatars,
# display names) of other users through the client API. Defaults to
# 'false'. Note that profile data is also available via the federation
# API, unless allow_profile_lookup_over_federation is set to false.
#
#require_auth_for_profile_requests: true
# Uncomment to require a user to share a room with another user in order
# to retrieve their profile information. Only checked on Client-Server
# requests. Profile requests from other servers should be checked by the
# requesting server. Defaults to 'false'.
#
#limit_profile_requests_to_users_who_share_rooms: true
# Uncomment to prevent a user's profile data from being retrieved and
# displayed in a room until they have joined it. By default, a user's
# profile data is included in an invite event, regardless of the values
# of the above two settings, and whether or not the users share a server.
# Defaults to 'true'.
#
#include_profile_data_on_invite: false
# If set to 'true', removes the need for authentication to access the server's
# public rooms directory through the client API, meaning that anyone can
# query the room directory. Defaults to 'false'.
#
#allow_public_rooms_without_auth: true
# If set to 'true', allows any other homeserver to fetch the server's public
# rooms directory via federation. Defaults to 'false'.
#
#allow_public_rooms_over_federation: true
# The default room version for newly created rooms.
#
# Known room versions are listed here:
# https://spec.matrix.org/latest/rooms/#complete-list-of-room-versions
#
# For example, for room version 1, default_room_version should be set
# to &quot;1&quot;.
#
#default_room_version: &quot;6&quot;
# The GC threshold parameters to pass to `gc.set_threshold`, if defined
#
#gc_thresholds: [700, 10, 10]
# The minimum time in seconds between each GC for a generation, regardless of
# the GC thresholds. This ensures that we don't do GC too frequently.
#
# A value of `[1s, 10s, 30s]` indicates that a second must pass between consecutive
# generation 0 GCs, etc.
#
# Defaults to `[1s, 10s, 30s]`.
#
#gc_min_interval: [0.5s, 30s, 1m]
# Set the limit on the returned events in the timeline in the get
# and sync operations. The default value is 100. -1 means no upper limit.
#
# Uncomment the following to increase the limit to 5000.
#
#filter_timeline_limit: 5000
# Whether room invites to users on this server should be blocked
# (except those sent by local server admins). The default is False.
#
#block_non_admin_invites: true
# Room searching
#
# If disabled, new messages will not be indexed for searching and users
# will receive errors when searching for messages. Defaults to enabled.
#
#enable_search: false
# Prevent outgoing requests from being sent to the following blacklisted IP address
# CIDR ranges. If this option is not specified then it defaults to private IP
# address ranges (see the example below).
#
# The blacklist applies to the outbound requests for federation, identity servers,
# push servers, and for checking key validity for third-party invite events.
#
# (0.0.0.0 and :: are always blacklisted, whether or not they are explicitly
# listed here, since they correspond to unroutable addresses.)
#
# This option replaces federation_ip_range_blacklist in Synapse v1.25.0.
#
# Note: The value is ignored when an HTTP proxy is in use
#
#ip_range_blacklist:
# - '127.0.0.0/8'
# - '10.0.0.0/8'
# - '172.16.0.0/12'
# - '192.168.0.0/16'

# - 'fc00::/7'
# - '2001:db8::/32'
# - 'ff00::/8'
# - 'fec0::/10'
# List of IP address CIDR ranges that should be allowed for federation,
# identity servers, push servers, and for checking key validity for
# third-party invite events. This is useful for specifying exceptions to
# wide-ranging blacklisted target IP ranges - e.g. for communication with
# a push server only visible in your network.
#
# This whitelist overrides ip_range_blacklist and defaults to an empty
# list.
#
#ip_range_whitelist:
# - '192.168.1.1'
# List of ports that Synapse should listen on, their purpose and their
# configuration.
#
# Options for each listener include:
#
# port: the TCP port to bind to
#
# bind_addresses: a list of local addresses to listen on. The default is
# 'all local interfaces'.
#
# type: the type of listener. Normally 'http', but other valid options are:
# 'manhole' (see https://matrix-org.github.io/synapse/latest/manhole.html),
# 'metrics' (see https://matrix-org.github.io/synapse/latest/metrics-howto.html),
# 'replication' (see https://matrix-org.github.io/synapse/latest/workers.html).
#
# tls: set to true to enable TLS for this listener. Will use the TLS
# key/cert specified in tls_private_key_path / tls_certificate_path.
#
# x_forwarded: Only valid for an 'http' listener. Set to true to use the
# X-Forwarded-For header as the client IP. Useful when Synapse is
# behind a reverse-proxy.
#
# resources: Only valid for an 'http' listener. A list of resources to host
# on this port. Options for each resource are:
#
# names: a list of names of HTTP resources. See below for a list of
# valid resource names.
#
# compress: set to true to enable HTTP compression for this resource.
#
# additional_resources: Only valid for an 'http' listener. A map of
# additional endpoints which should be loaded via dynamic modules.
#
# Valid resource names are:
#
# client: the client-server API (/_matrix/client), and the synapse admin
# API (/_synapse/admin). Also implies 'media' and 'static'.
#
# consent: user consent forms (/_matrix/consent).
# See https://matrix-org.github.io/synapse/latest/consent_tracking.html.
#
# federation: the server-server API (/_matrix/federation). Also implies
# 'media', 'keys', 'openid'
#
# keys: the key discovery API (/_matrix/keys).
#
# media: the media API (/_matrix/media).
#
# metrics: the metrics interface.
# See https://matrix-org.github.io/synapse/latest/metrics-howto.html.
#
# openid: OpenID authentication.
#
# replication: the HTTP replication API (/_synapse/replication).
# See https://matrix-org.github.io/synapse/latest/workers.html.
#
# static: static resources under synapse/static (/_matrix/static). (Mostly
# useful for 'fallback authentication'.)
#
listeners:
# TLS-enabled listener: for when matrix traffic is sent directly to synapse.
#
# Disabled by default. To enable it, uncomment the following. (Note that you
# will also need to give Synapse a TLS key and certificate: see the TLS section
# below.)
#
#- port: 8448
# type: http
# tls: true
# resources:
# - names: [client, federation]
# Unsecure HTTP listener: for when matrix traffic passes through a reverse proxy
# that unwraps TLS.
#
# If you plan to use a reverse proxy, please see
# https://matrix-org.github.io/synapse/latest/reverse_proxy.html.
#

# Connection settings for the manhole
#
manhole_settings:
# The username for the manhole. This defaults to 'matrix'.
#
#username: manhole
# The password for the manhole. This defaults to 'rabbithole'.
#
#password: mypassword
# The private and public SSH key pair used to encrypt the manhole traffic.
# If these are left unset, then hardcoded and non-secret keys are used,
# which could allow traffic to be intercepted if sent over a public network.
#
#ssh_priv_key_path: CONFDIR/id_rsa
#ssh_pub_key_path: CONFDIR/id_rsa.pub
# Forward extremities can build up in a room due to networking delays between
# homeservers. Once this happens in a large room, calculation of the state of
# that room can become quite expensive. To mitigate this, once the number of
# forward extremities reaches a given threshold, Synapse will send an
# org.matrix.dummy_event event, which will reduce the forward extremities
# in the room.
#
# This setting defines the threshold (i.e. number of forward extremities in the
# room) at which dummy events are sent. The default value is 10.
#
#dummy_events_threshold: 5
## Homeserver blocking ##
# How to reach the server admin, used in ResourceLimitError
#
#admin_contact: 'mailto:admin@server.com'
# Global blocking
#
#hs_disabled: false
#hs_disabled_message: 'Human readable reason for why the HS is blocked'
# Monthly Active User Blocking
#
# Used in cases where the admin or server owner wants to limit to the
# number of monthly active users.
#
# 'limit_usage_by_mau' disables/enables monthly active user blocking. When
# enabled and a limit is reached the server returns a 'ResourceLimitError'
# with error type Codes.RESOURCE_LIMIT_EXCEEDED
#
# 'max_mau_value' is the hard limit of monthly active users above which
# the server will start blocking user actions.
#
# 'mau_trial_days' is a means to add a grace period for active users. It
# means that users must be active for this number of days before they
# can be considered active and guards against the case where lots of users
# sign up in a short space of time never to return after their initial
# session.
#
# 'mau_limit_alerting' is a means of limiting client side alerting
# should the mau limit be reached. This is useful for small instances
# where the admin has 5 mau seats (say) for 5 specific people and no
# interest increasing the mau limit further. Defaults to True, which
# means that alerting is enabled
#
#limit_usage_by_mau: false
#max_mau_value: 50
#mau_trial_days: 2
#mau_limit_alerting: false
# If enabled, the metrics for the number of monthly active users will
# be populated, however no one will be limited. If limit_usage_by_mau
# is true, this is implied to be true.
#
#mau_stats_only: false
# Sometimes the server admin will want to ensure certain accounts are
# never blocked by mau checking. These accounts are specified here.
#
#mau_limit_reserved_threepids:
# - medium: 'email'
# address: 'reserved_user@example.com'
# Used by phonehome stats to group together related servers.
#server_context: context
# Resource-constrained homeserver settings
#
# When this is enabled, the room &quot;complexity&quot; will be checked before a user
# joins a new remote room. If it is above the complexity limit, the server will
# disallow joining, or will instantly leave.

# Message retention policy at the server level.
#
# Room admins and mods can define a retention period for their rooms using the
# 'm.room.retention' state event, and server admins can cap this period by setting
# the 'allowed_lifetime_min' and 'allowed_lifetime_max' config options.
#
# If this feature is enabled, Synapse will regularly look for and purge events
# which are older than the room's maximum retention period. Synapse will also
# filter events received over federation so that events that should have been
# purged are ignored and not stored again.
#
retention:
# The message retention policies feature is disabled by default. Uncomment the
# following line to enable it.
#
#enabled: true
# Default retention policy. If set, Synapse will apply it to rooms that lack the
# 'm.room.retention' state event. Currently, the value of 'min_lifetime' doesn't
# matter much because Synapse doesn't take it into account yet.
#
#default_policy:
# min_lifetime: 1d
# max_lifetime: 1y
# Retention policy limits. If set, and the state of a room contains a
# 'm.room.retention' event in its state which contains a 'min_lifetime' or a
# 'max_lifetime' that's out of these bounds, Synapse will cap the room's policy
# to these limits when running purge jobs.
#
#allowed_lifetime_min: 1d
#allowed_lifetime_max: 1y
# Server admins can define the settings of the background jobs purging the
# events which lifetime has expired under the 'purge_jobs' section.
#
# If no configuration is provided, a single job will be set up to delete expired
# events in every room daily.
#
# Each job's configuration defines which range of message lifetimes the job
# takes care of. For example, if 'shortest_max_lifetime' is '2d' and
# 'longest_max_lifetime' is '3d', the job will handle purging expired events in
# rooms whose state defines a 'max_lifetime' that's both higher than 2 days, and
# lower than or equal to 3 days. Both the minimum and the maximum value of a
# range are optional, e.g. a job with no 'shortest_max_lifetime' and a
# 'longest_max_lifetime' of '3d' will handle every room with a retention policy
# which 'max_lifetime' is lower than or equal to three days.
#
# The rationale for this per-job configuration is that some rooms might have a
# retention policy with a low 'max_lifetime', where history needs to be purged
# of outdated messages on a more frequent basis than for the rest of the rooms
# (e.g. every 12h), but not want that purge to be performed by a job that's
# iterating over every room it knows, which could be heavy on the server.
#
# If any purge job is configured, it is strongly recommended to have at least
# a single job with neither 'shortest_max_lifetime' nor 'longest_max_lifetime'
# set, or one job without 'shortest_max_lifetime' and one job without
# 'longest_max_lifetime' set. Otherwise some rooms might be ignored, even if
# 'allowed_lifetime_min' and 'allowed_lifetime_max' are set, because capping a
# room's policy to these values is done after the policies are retrieved from
# Synapse's database (which is done using the range specified in a purge job's
# configuration).
#
#purge_jobs:
# - longest_max_lifetime: 3d
# interval: 12h
# - shortest_max_lifetime: 3d
# interval: 1d
## TLS ##
# PEM-encoded X509 certificate for TLS.
# This certificate, as of Synapse 1.0, will need to be a valid and verifiable
# certificate, signed by a recognised Certificate Authority.
#
# Be sure to use a `.pem` file that includes the full certificate chain including
# any intermediate certificates (for instance, if using certbot, use
# `fullchain.pem` as your certificate, not `cert.pem`).
#
#tls_certificate_path: &quot;CONFDIR/SERVERNAME.tls.crt&quot;
# PEM-encoded private key for TLS
#
#tls_private_key_path: &quot;CONFDIR/SERVERNAME.tls.key&quot;
# Whether to verify TLS server certificates for outbound federation requests.
#
# Defaults to `true`. To disable certificate verification, uncomment the
# following line.
#
#federation_verify_certificates: false
# The minimum TLS version that will be used for outbound federation requests.
#
# Defaults to `1`. Configurable to `1`, `1.1`, `1.2`, or `1.3`. Note
# that setting this value higher than `1.2` will prevent federation to most
# of the public Matrix network: only configure it to `1.3` if you have an
# entirely private federation setup and you can ensure TLS 1.3 support.
#
#federation_client_minimum_tls_version: 1.2
# Skip federation certificate verification on the following whitelist
# of domains.
#
# This setting should only be used in very specific cases, such as
# federation over Tor hidden services and similar. For private networks
# of homeservers, you likely want to use a private CA instead.
#
# Only effective if federation_verify_certicates is `true`.
#
#federation_certificate_verification_whitelist:
# - lon.example.com
# - &quot;*.domain.com&quot;

## Federation ##
# Restrict federation to the following whitelist of domains.
# N.B. we recommend also firewalling your federation listener to limit
# inbound federation traffic as early as possible, rather than relying
# purely on this application-layer restriction. If not specified, the
# default is to whitelist everything.
#
#federation_domain_whitelist:
# - lon.example.com
# - nyc.example.com
# - syd.example.com
# Report prometheus metrics on the age of PDUs being sent to and received from
# the following domains. This can be used to give an idea of &quot;delay&quot; on inbound
# and outbound federation, though be aware that any delay can be due to problems
# at either end or with the intermediate network.

## Caching ##
# Caching can be configured through the following options.
#
# A cache 'factor' is a multiplier that can be applied to each of
# Synapse's caches in order to increase or decrease the maximum
# number of entries that can be stored.
# The number of events to cache in memory. Not affected by
# caches.global_factor.
#
#event_cache_size: 10K
caches:
# Controls the global cache factor, which is the default cache factor
# for all caches if a specific factor for that cache is not otherwise
# set.
#
# This can also be set by the &quot;SYNAPSE_CACHE_FACTOR&quot; environment
# variable. Setting by environment variable takes priority over
# setting through the config file.
#
# Defaults to 0.5, which will half the size of all caches.
#
#global_factor: 1.0
# A dictionary of cache name to cache factor for that individual
# cache. Overrides the global cache factor for a given cache.
#
# These can also be set through environment variables comprised
# of &quot;SYNAPSE_CACHE_FACTOR_&quot; + the name of the cache in capital
# letters and underscores. Setting by environment variable
# takes priority over setting through the config file.
# Ex. SYNAPSE_CACHE_FACTOR_GET_USERS_WHO_SHARE_ROOM_WITH_USER=2.0
#
# Some caches have '*' and other characters that are not
# alphanumeric or underscores. These caches can be named with or
# without the special characters stripped. For example, to specify
# the cache factor for `*stateGroupCache*` via an environment
# variable would be `SYNAPSE_CACHE_FACTOR_STATEGROUPCACHE=2.0`.
#
per_cache_factors:
#get_users_who_share_room_with_user: 2.0
# Controls how long an entry can be in a cache without having been
# accessed before being evicted. Defaults to None, which means
# entries are never evicted based on time.
#
#expiry_time: 30m
# Controls how long the results of a /sync request are cached for after
# a successful response is returned. A higher duration can help clients with
# intermittent connections, at the cost of higher memory usage.
#
# By default, this is zero, which means that sync responses are not cached
# at all.
#
#sync_response_cache_duration: 2m
## Database ##
# The 'database' setting defines the database that synapse uses to store all of
# its data.
#
# 'name' gives the database engine to use: either 'sqlite3' (for SQLite) or
# 'psycopg2' (for PostgreSQL).
#
# 'txn_limit' gives the maximum number of transactions to run per connection
# before reconnecting. Defaults to 0, which means no limit.
#
# 'args' gives options which are passed through to the database engine,
# except for options starting 'cp_', which are used to configure the Twisted
# connection pool. For a reference to valid arguments, see:
# * for sqlite: https://docs.python.org/3/library/sqlite3.html#sqlite3.connect

# https://docs.python.org/3.7/library/logging.config.html#configuration-dictionary-schema
#
log_config: &quot;CONFDIR/SERVERNAME.log.config&quot;
## Ratelimiting ##
# Ratelimiting settings for client actions (registration, login, messaging).
#
# Each ratelimiting configuration is made of two parameters:
# - per_second: number of requests a client can send per second.
# - burst_count: number of requests a client can send before being throttled.
#
# Synapse currently uses the following configurations:
# - one for messages that ratelimits sending based on the account the client
# is using
# - one for registration that ratelimits registration requests based on the
# client's IP address.
# - one for checking the validity of registration tokens that ratelimits
# requests based on the client's IP address.
# - one for login that ratelimits login requests based on the client's IP
# address.
# - one for login that ratelimits login requests based on the account the
# client is attempting to log into.
# - one for login that ratelimits login requests based on the account the
# client is attempting to log into, based on the amount of failed login
# attempts for this account.
# - one for ratelimiting redactions by room admins. If this is not explicitly
# set then it uses the same ratelimiting as per rc_message. This is useful
# to allow room admins to deal with abuse quickly.
# - two for ratelimiting number of rooms a user can join, &quot;local&quot; for when
# users are joining rooms the server is already in (this is cheap) vs
# &quot;remote&quot; for when users are trying to join rooms not on the server (which
# can be more expensive)
# - one for ratelimiting how often a user or IP can attempt to validate a 3PID.
# - two for ratelimiting how often invites can be sent in a room or to a
# specific user.
#
# The defaults are as shown below.
#
#rc_message:
# per_second: 0.2
# burst_count: 10

# Ratelimiting settings for incoming federation
#
# The rc_federation configuration is made up of the following settings:
# - window_size: window size in milliseconds
# - sleep_limit: number of federation requests from a single server in
# a window before the server will delay processing the request.
# - sleep_delay: duration in milliseconds to delay processing events
# from remote servers by if they go over the sleep limit.
# - reject_limit: maximum number of concurrent federation requests
# allowed from a single server
# - concurrent: number of federation requests to concurrently process
# from a single server
#
# The defaults are as shown below.
#
#rc_federation:
# window_size: 1000
# sleep_limit: 10
# sleep_delay: 500
# reject_limit: 50
# concurrent: 3
# Target outgoing federation transaction frequency for sending read-receipts,

#
#url_preview_enabled: true
# List of IP address CIDR ranges that the URL preview spider is denied

# synapse to issue arbitrary GET requests to your internal services,
# causing serious security issues.
#
# (0.0.0.0 and :: are always blacklisted, whether or not they are explicitly
# listed here, since they correspond to unroutable addresses.)
#
# This must be specified if url_preview_enabled is set. It is recommended that

#
# Each list entry is a dictionary of url component attributes as returned
# by urlparse.urlsplit as applied to the absolute form of the URL. See

#
# By default, any room aliases included in this list will be created
# as a publicly joinable room when the first user registers for the
# homeserver. This behaviour can be customised with the settings below.
# If the room already exists, make certain it is a publicly joinable
# room. The join rule of the room must be set to 'public'.
#
#auto_join_rooms:
# - &quot;#example:example.com&quot;
# Where auto_join_rooms are specified, setting this flag ensures that the
# the rooms exist by creating them when the first user on the
# homeserver registers.
#
# By default the auto-created rooms are publicly joinable from any federated
# server. Use the autocreate_auto_join_rooms_federated and
# autocreate_auto_join_room_preset settings below to customise this behaviour.
#
# Setting to false means that if the rooms are not manually created,

#
#autocreate_auto_join_rooms: false
# Whether the auto_join_rooms that are auto-created are available via

#
#autocreate_auto_join_rooms_federated: false
# The room preset to use when auto-creating one of auto_join_rooms. Only has an

#
# This can be one of &quot;public_chat&quot;, &quot;private_chat&quot;, or &quot;trusted_private_chat&quot;.
# If a value of &quot;private_chat&quot; or &quot;trusted_private_chat&quot; is used then
# auto_join_mxid_localpart must also be configured.
#
# Defaults to &quot;public_chat&quot;, meaning that the room is joinable by anyone, including
# federated servers if autocreate_auto_join_rooms_federated is true (the default).
# Uncomment the following to require an invitation to join these rooms.
#
#autocreate_auto_join_room_preset: private_chat
# The local part of the user id which is used to create auto_join_rooms if

#
# The user id is also used to invite new users to any auto-join rooms which

# Enable sentry integration
# NOTE: While attempts are made to ensure that the logs don't contain

## API Configuration ##
# Controls for the state that is shared with users who receive an invite
# to a room
#
room_prejoin_state:
# By default, the following state event types are shared with users who
# receive invites to the room:
#
# - m.room.join_rules
# - m.room.canonical_alias
# - m.room.avatar
# - m.room.encryption
# - m.room.name
# - m.room.create
# - m.room.topic
#
# Uncomment the following to disable these defaults (so that only the event
# types listed in 'additional_event_types' are shared). Defaults to 'false'.
#
#disable_default_event_types: true
# Additional state event types to share with users when they are invited
# to a room.
#
# By default, this list is empty (so only the default event types are shared).
#
#additional_event_types:
# - org.example.custom.event.type
# We record the IP address of clients used to access the API for various
# reasons, including displaying it to the user in the &quot;Where you're signed in&quot;
# dialog.
#
# By default, when puppeting another user via the admin API, the client IP
# address is recorded against the user who created the access token (ie, the
# admin user), and *not* the puppeted user.
#
# Uncomment the following to also record the IP address against the puppeted
# user. (This also means that the puppeted user will count as an &quot;active&quot; user
# for the purpose of monthly active user tracking - see 'limit_usage_by_mau' etc
# above.)
#
#track_puppeted_user_ips: true
# A list of application service config files to use

# a secret which is used to calculate HMACs for form values, to stop
# falsification of values. Must be specified for the User Consent
# forms to work.
#
#form_secret: &lt;PRIVATE STRING&gt;
## Signing Keys ##
# Path to the signing key to sign messages with
#
signing_key_path: &quot;CONFDIR/SERVERNAME.signing.key&quot;
# The keys that the server used to sign messages with but won't use
# to sign new messages.
#
old_signing_keys:
# For each key, `key` should be the base64-encoded public key, and
# `expired_ts`should be the time (in milliseconds since the unix epoch) that
# it was last used.
#
# It is possible to build an entry from an old signing.key file using the
# `export_signing_key` script which is provided with synapse.
#
# For example:
#
#&quot;ed25519:id&quot;: { key: &quot;base64string&quot;, expired_ts: 123456789123 }
# How long key response published by this server is valid for.
# Used to set the valid_until_ts in /key/v2 APIs.
# Determines how quickly servers will query to check which keys
# are still valid.
#
#key_refresh_interval: 1d
# The trusted servers to download signing keys from.
#
# When we need to fetch a signing key, each server is tried in parallel.
#
# Normally, the connection to the key server is validated via TLS certificates.
# Additional security can be provided by configuring a `verify key`, which
# will make synapse check that the response is signed by that key.
#
# This setting supercedes an older setting named `perspectives`. The old format
# is still supported for backwards-compatibility, but it is deprecated.
#
# 'trusted_key_servers' defaults to matrix.org, but using it will generate a
# warning on start-up. To suppress this warning, set
# 'suppress_key_server_warning' to true.
#
# Options for each entry in the list include:
#
# server_name: the name of the server. required.
#
# verify_keys: an optional map from key id to base64-encoded public key.
# If specified, we will check that the response is signed by at least
# one of the given keys.
#
# accept_keys_insecurely: a boolean. Normally, if `verify_keys` is unset,
# and federation_verify_certificates is not `true`, synapse will refuse
# to start, because this would allow anyone who can spoof DNS responses
# to masquerade as the trusted key server. If you know what you are doing
# and are sure that your network environment provides a secure connection
# to the key server, you can set this to `true` to override this
# behaviour.
#
# An example configuration might look like:
#
#trusted_key_servers:
# - server_name: &quot;my_trusted_server.example.com&quot;
# verify_keys:
# &quot;ed25519:auto&quot;: &quot;abcdefghijklmnopqrstuvwxyzabcdefghijklmopqr&quot;
# - server_name: &quot;my_other_trusted_server.example.com&quot;
#
trusted_key_servers:
- server_name: &quot;matrix.org&quot;
# Uncomment the following to disable the warning that is emitted when the
# trusted_key_servers include 'matrix.org'. See above.
#
#suppress_key_server_warning: true
# The signing keys to use when acting as a trusted key server. If not specified
# defaults to the server signing key.
#
# Can contain multiple keys, one per line.
#
#key_server_signing_keys_path: &quot;key_server_signing_keys.key&quot;
## Single sign-on integration ##
# The following settings can be used to make Synapse use a single sign-on
# provider for authentication, instead of its internal password database.
#
# You will probably also want to set the following options to `false` to
# disable the regular login/registration flows:
# * enable_registration
# * password_config.enabled
#
# You will also want to investigate the settings under the &quot;sso&quot; configuration
# section below.
# Enable SAML2 for registration and login. Uses pysaml2.
#
# At least one of `sp_config` or `config_path` must be set in this section to
# enable SAML login.
#
# Once SAML support is enabled, a metadata file will be exposed at
# https://&lt;server&gt;:&lt;port&gt;/_synapse/client/saml2/metadata.xml, which you may be able to
# use to configure your SAML IdP with. Alternatively, you can manually configure
# the IdP to use an ACS location of
# https://&lt;server&gt;:&lt;port&gt;/_synapse/client/saml2/authn_response.
#
saml2_config:
# `sp_config` is the configuration for the pysaml2 Service Provider.
# See pysaml2 docs for format of config.
#
# Default values will be used for the 'entityid' and 'service' settings,
# so it is not normally necessary to specify them unless you need to
# override them.
#
sp_config:
# Point this to the IdP's metadata. You must provide either a local
# file via the `local` attribute or (preferably) a URL via the
# `remote` attribute.
#
#metadata:
# local: [&quot;saml2/idp.xml&quot;]
# remote:
# - url: https://our_idp/metadata.xml
# Allowed clock difference in seconds between the homeserver and IdP.
#
# Uncomment the below to increase the accepted time difference from 0 to 3 seconds.
#
#accepted_time_diff: 3
# By default, the user has to go to our login page first. If you'd like
# to allow IdP-initiated login, set 'allow_unsolicited: true' in a
# 'service.sp' section:
#
#service:
# sp:
# allow_unsolicited: true
# The examples below are just used to generate our metadata xml, and you
# may well not need them, depending on your setup. Alternatively you
# may need a whole lot more detail - see the pysaml2 docs!

# using a custom module. This section will be passed as a Python
# dictionary to the module's `parse_config` method.
#
config:
# The SAML attribute (after mapping via the attribute maps) to use
# to derive the Matrix ID from. 'uid' by default.
#
# Note: This used to be configured by the
# saml2_config.mxid_source_attribute option. If that is still
# defined, its value will be used instead.
#
#mxid_source_attribute: displayName
# The mapping system to use for mapping the saml attribute onto a
# matrix ID.
#
# Options include:
# * 'hexencode' (which maps unpermitted characters to '=xx')
# * 'dotreplace' (which replaces unpermitted characters with
# '.').
# The default is 'hexencode'.
#
# Note: This used to be configured by the
# saml2_config.mxid_mapping option. If that is still defined, its
# value will be used instead.
#
#mxid_mapping: dotreplace
# In previous versions of synapse, the mapping from SAML attribute to
# MXID was always calculated dynamically rather than stored in a
# table. For backwards- compatibility, we will look for user_ids
# matching such a pattern before creating a new account.
#
# This setting controls the SAML attribute which will be used for this
# backwards-compatibility lookup. Typically it should be 'uid', but if
# the attribute maps are changed, it may be necessary to change it.
#
# The default is 'uid'.
#
#grandfathered_mxid_source_attribute: upn
# It is possible to configure Synapse to only allow logins if SAML attributes
# match particular values. The requirements can be listed under
# `attribute_requirements` as shown below. All of the listed attributes must
# match for the login to be permitted.
#
#attribute_requirements:
# - attribute: userGroup
# value: &quot;staff&quot;
# - attribute: department
# value: &quot;sales&quot;
# If the metadata XML contains multiple IdP entities then the `idp_entityid`
# option must be set to the entity to redirect users to.
#
# Most deployments only have a single IdP entity and so should omit this
# option.
#
#idp_entityid: 'https://our_idp/entityid'
# List of OpenID Connect (OIDC) / OAuth 2.0 identity providers, for registration
# and login.
#
# Options for each entry include:
#
# idp_id: a unique identifier for this identity provider. Used internally
# by Synapse; should be a single word such as 'github'.
#
# Note that, if this is changed, users authenticating via that provider
# will no longer be recognised as the same user!
#
# (Use &quot;oidc&quot; here if you are migrating from an old &quot;oidc_config&quot;
# configuration.)
#
# idp_name: A user-facing name for this identity provider, which is used to
# offer the user a choice of login mechanisms.
#
# idp_icon: An optional icon for this identity provider, which is presented
# by clients and Synapse's own IdP picker page. If given, must be an
# MXC URI of the format mxc://&lt;server-name&gt;/&lt;media-id&gt;. (An easy way to
# obtain such an MXC URI is to upload an image to an (unencrypted) room
# and then copy the &quot;url&quot; from the source of the event.)
#
# idp_brand: An optional brand for this identity provider, allowing clients
# to style the login flow according to the identity provider in question.
# See the spec for possible options here.
#
# discover: set to 'false' to disable the use of the OIDC discovery mechanism
# to discover endpoints. Defaults to true.
#
# issuer: Required. The OIDC issuer. Used to validate tokens and (if discovery
# is enabled) to discover the provider's endpoints.
#
# client_id: Required. oauth2 client id to use.
#
# client_secret: oauth2 client secret to use. May be omitted if
# client_secret_jwt_key is given, or if client_auth_method is 'none'.
#
# client_secret_jwt_key: Alternative to client_secret: details of a key used
# to create a JSON Web Token to be used as an OAuth2 client secret. If
# given, must be a dictionary with the following properties:
#
# key: a pem-encoded signing key. Must be a suitable key for the
# algorithm specified. Required unless 'key_file' is given.
#
# key_file: the path to file containing a pem-encoded signing key file.
# Required unless 'key' is given.
#
# jwt_header: a dictionary giving properties to include in the JWT
# header. Must include the key 'alg', giving the algorithm used to
# sign the JWT, such as &quot;ES256&quot;, using the JWA identifiers in
# RFC7518.
#
# jwt_payload: an optional dictionary giving properties to include in
# the JWT payload. Normally this should include an 'iss' key.
#
# client_auth_method: auth method to use when exchanging the token. Valid
# values are 'client_secret_basic' (default), 'client_secret_post' and
# 'none'.
#
# scopes: list of scopes to request. This should normally include the &quot;openid&quot;
# scope. Defaults to [&quot;openid&quot;].
#
# authorization_endpoint: the oauth2 authorization endpoint. Required if
# provider discovery is disabled.
#
# token_endpoint: the oauth2 token endpoint. Required if provider discovery is
# disabled.
#
# userinfo_endpoint: the OIDC userinfo endpoint. Required if discovery is
# disabled and the 'openid' scope is not requested.
#
# jwks_uri: URI where to fetch the JWKS. Required if discovery is disabled and
# the 'openid' scope is used.
#
# skip_verification: set to 'true' to skip metadata verification. Use this if
# you are connecting to a provider that is not OpenID Connect compliant.
# Defaults to false. Avoid this in production.
#
# user_profile_method: Whether to fetch the user profile from the userinfo
# endpoint, or to rely on the data returned in the id_token from the
# token_endpoint.
#
# Valid values are: 'auto' or 'userinfo_endpoint'.
#
# Defaults to 'auto', which uses the userinfo endpoint if 'openid' is
# not included in 'scopes'. Set to 'userinfo_endpoint' to always use the
# userinfo endpoint.
#
# allow_existing_users: set to 'true' to allow a user logging in via OIDC to
# match a pre-existing account instead of failing. This could be used if
# switching from password logins to OIDC. Defaults to false.
#
# user_mapping_provider: Configuration for how attributes returned from a OIDC
# provider are mapped onto a matrix user. This setting has the following
# sub-properties:
#
# module: The class name of a custom mapping module. Default is
# 'synapse.handlers.oidc.JinjaOidcMappingProvider'.
# See https://matrix-org.github.io/synapse/latest/sso_mapping_providers.html#openid-mapping-providers
# for information on implementing a custom mapping provider.
#
# config: Configuration for the mapping provider module. This section will
# be passed as a Python dictionary to the user mapping provider
# module's `parse_config` method.
#
# For the default provider, the following settings are available:
#
# subject_claim: name of the claim containing a unique identifier
# for the user. Defaults to 'sub', which OpenID Connect
# compliant providers should provide.
#
# localpart_template: Jinja2 template for the localpart of the MXID.
# If this is not set, the user will be prompted to choose their
# own username (see 'sso_auth_account_details.html' in the 'sso'
# section of this file).
#
# display_name_template: Jinja2 template for the display name to set
# on first login. If unset, no displayname will be set.
#
# email_template: Jinja2 template for the email address of the user.
# If unset, no email address will be added to the account.
#
# extra_attributes: a map of Jinja2 templates for extra attributes
# to send back to the client during login.
# Note that these are non-standard and clients will ignore them
# without modifications.
#
# When rendering, the Jinja2 templates are given a 'user' variable,
# which is set to the claims returned by the UserInfo Endpoint and/or
# in the ID Token.
#
# It is possible to configure Synapse to only allow logins if certain attributes
# match particular values in the OIDC userinfo. The requirements can be listed under
# `attribute_requirements` as shown below. All of the listed attributes must
# match for the login to be permitted. Additional attributes can be added to
# userinfo by expanding the `scopes` section of the OIDC config to retrieve
# additional information from the OIDC provider.
#
# If the OIDC claim is a list, then the attribute must match any value in the list.
# Otherwise, it must exactly match the value of the claim. Using the example
# below, the `family_name` claim MUST be &quot;Stephensson&quot;, but the `groups`
# claim MUST contain &quot;admin&quot;.
#
# attribute_requirements:
# - attribute: family_name
# value: &quot;Stephensson&quot;
# - attribute: groups
# value: &quot;admin&quot;
#
# See https://matrix-org.github.io/synapse/latest/openid.html
# for information on how to configure these options.
#
# For backwards compatibility, it is also possible to configure a single OIDC

sso:
# A list of client URLs which are whitelisted so that the user does not

# whose URL starts with an entry in the following list will not be subject
# to an additional confirmation step after the SSO login is completed.
#
# WARNING: An entry such as &quot;https://my.client&quot; is insecure, because it
# will also match &quot;https://my.client.evil.site&quot;, exposing your users to
# phishing attacks from evil.site. To avoid this, include a slash after the
# hostname: &quot;https://my.client/&quot;.
#
# The login fallback page (used by clients that don't natively support the

#
# This defaults to 0, meaning the user is queried for their credentials

## Push ##
push:
# Clients requesting push notifications can either have the body of
# the message sent in the notification poke along with other details
# like the sender, or just the event ID and room ID (`event_id_only`).
# If clients choose the former, this option controls whether the
# notification request includes the content of the event (other details
# like the sender are still included). For `event_id_only` push, it
# has no effect.
#
# For modern android devices the notification content will still appear
# because it is loaded by the app. iPhone, however will send a
# notification saying only that a message arrived and who it came from.
#
# The default value is &quot;true&quot; to include message details. Uncomment to only
# include the event ID and room ID in push notification payloads.
#
#include_content: false
# When a push notification is received, an unread count is also sent.
# This number can either be calculated as the number of unread messages
# for the user, or the number of *rooms* the user has unread messages in.
#
# The default value is &quot;true&quot;, meaning push clients will see the number of
# rooms with unread messages in them. Uncomment to instead send the number
# of unread messages.
#
#group_unread_count_by_room: false
## Rooms ##
# Controls whether locally-created rooms should be end-to-end encrypted by
# default.
#
# Possible options are &quot;all&quot;, &quot;invite&quot;, and &quot;off&quot;. They are defined as:
#
# * &quot;all&quot;: any locally-created room
# * &quot;invite&quot;: any room created with the &quot;private_chat&quot; or &quot;trusted_private_chat&quot;
# room creation presets
# * &quot;off&quot;: this option will take no effect
#
# The default value is &quot;off&quot;.
#
# Note that this option will only affect rooms created after it is set. It
# will also not affect rooms created by other servers.
#
#encryption_enabled_by_default_for_room_type: invite
# Uncomment to allow non-server-admin users to create groups on this server

# Uncomment to disable the user directory.
#
#enabled: false
# Defines whether to search all users visible to your HS when searching
# the user directory. If false, search results will only contain users
# visible in public rooms and users sharing a room with the requester.
# Defaults to false.
#
# NB. If you set this to true, and the last time the user_directory search
# indexes were (re)built was before Synapse 1.44, you'll have to
# rebuild the indexes in order to search through all known users.
# These indexes are built the first time Synapse starts; admins can
# manually trigger a rebuild via API following the instructions at
# https://matrix-org.github.io/synapse/latest/usage/administration/admin_api/background_updates.html#run
#
# Uncomment to return search results containing all known users, even if that
# user does not share a room with the requester.
#
#search_all_users: true
# Defines whether to prefer local users in search query results.
# If True, local users are more likely to appear above remote users
# when searching the user directory. Defaults to false.
#
# Uncomment to prefer local over remote users in user directory search
# results.
#
#prefer_local_users: true
# User Consent configuration
#
# for detailed instructions, see
# https://matrix-org.github.io/synapse/latest/consent_tracking.html
#
# Parts of this section are required if enabling the 'consent' resource under
# 'listeners', in particular 'template_dir' and 'version'.
#
# 'template_dir' gives the location of the templates for the HTML forms.
# This directory should contain one subdirectory per language (eg, 'en', 'fr'),
# and each language directory should contain the policy document (named as
# '&lt;version&gt;.html') and a success page (success.html).
#
# 'version' specifies the 'current' version of the policy document. It defines
# the version to be served by the consent resource if there is no 'v'
# parameter.
#
# 'server_notice_content', if enabled, will send a user a &quot;Server Notice&quot;
# asking them to consent to the privacy policy. The 'server_notices' section
# must also be configured for this to work. Notices will *not* be sent to
# guest users unless 'send_server_notice_to_guests' is set to true.
#
# 'block_events_error', if set, will block any attempts to send events
# until the user consents to the privacy policy. The value of the setting is
# used as the text of the error.
#
# 'require_at_registration', if enabled, will add a step to the registration
# process, similar to how captcha works. Users will be required to accept the
# policy before their account is created.
#
# 'policy_name' is the display name of the policy users will see when registering
# for an account. Has no effect unless `require_at_registration` is enabled.
# Defaults to &quot;Privacy Policy&quot;.

#
#enable_room_list_search: false
# The `alias_creation` option controls who's allowed to create aliases
# on this server.
#
# The format of this option is a list of rules that contain globs that
# match against user_id, room_id and the new alias (fully qualified with
# server name). The action in the first rule that matches is taken,
# which can currently either be &quot;allow&quot; or &quot;deny&quot;.
#
# Missing user_id/room_id/alias fields default to &quot;*&quot;.
#
# If no rules match the request is denied. An empty list means no one
# can create aliases.
#
# Options for the rules include:
#
# user_id: Matches against the creator of the alias
# alias: Matches against the alias being created
# room_id: Matches against the room ID the alias is being pointed at
# action: Whether to &quot;allow&quot; or &quot;deny&quot; the request if the rule matches
#
# The default is:
#
#alias_creation_rules:
# - user_id: &quot;*&quot;
# alias: &quot;*&quot;
# room_id: &quot;*&quot;
# action: allow
# The `room_list_publication_rules` option controls who can publish and
# which rooms can be published in the public room list.
#
# The format of this option is the same as that for
# `alias_creation_rules`.
#
# If the room has one or more aliases associated with it, only one of
# the aliases needs to match the alias rule. If there are no aliases
# then only rules with `alias: *` match.
#
# If no rules match the request is denied. An empty list means no one
# can publish rooms.
#
# Options for the rules include:
#
# user_id: Matches against the creator of the alias
# room_id: Matches against the room ID being published
# alias: Matches against any current local or canonical aliases
# associated with the room
# action: Whether to &quot;allow&quot; or &quot;deny&quot; the request if the rule matches
#
# The default is:
