< p > Synapse comes with a non-standard login type to support
< a href = "https://en.wikipedia.org/wiki/JSON_Web_Token" > JSON Web Tokens< / a > . In general the
documentation for
< a href = "https://matrix.org/docs/spec/client_server/r0.6.1#login" > the login endpoint< / a >
is still valid (and the mechanism works similarly to the
< a href = "https://matrix.org/docs/spec/client_server/r0.6.1#token-based" > token based login< / a > ).< / p >
< p > To log in using a JSON Web Token, clients should submit a < code > /login< / code > request as
follows:< / p >
< pre > < code class = "language-json" > {
" type" : " org.matrix.login.jwt" ,
" token" : " < jwt> "
}
< / code > < / pre >
< p > Note that the login type of < code > m.login.jwt< / code > is supported, but is deprecated. This
will be removed in a future version of Synapse.< / p >
< p > The < code > token< / code > field should include the JSON web token with the following claims:< / p >
< ul >
2021-11-30 07:28:51 -07:00
< li > A claim that encodes the local part of the user ID is required. By default,
the < code > sub< / code > (subject) claim is used, or a custom claim can be set in the
configuration file.< / li >
2021-07-07 03:44:14 -06:00
< li > The expiration time (< code > exp< / code > ), not before time (< code > nbf< / code > ), and issued at (< code > iat< / code > )
claims are optional, but validated if present.< / li >
< li > The issuer (< code > iss< / code > ) claim is optional, but required and validated if configured.< / li >
< li > The audience (< code > aud< / code > ) claim is optional, but required and validated if configured.
Providing the audience claim when not configured will cause validation to fail.< / li >
< / ul >
< p > In the case that the token is not valid, the homeserver must respond with
< code > 403 Forbidden< / code > and an error code of < code > M_FORBIDDEN< / code > .< / p >
< p > As with other login types, there are additional fields (e.g. < code > device_id< / code > and
< code > initial_device_display_name< / code > ) which can be included in the above request.< / p >
< h2 id = "preparing-synapse" > < a class = "header" href = "#preparing-synapse" > Preparing Synapse< / a > < / h2 >
< p > The JSON Web Token integration in Synapse uses the
< a href = "https://pypi.org/project/pyjwt/" > < code > PyJWT< / code > < / a > library, which must be installed
as follows:< / p >
< ul >
< li >
< p > The relevant libraries are included in the Docker images and Debian packages
provided by < code > matrix.org< / code > so no further action is needed.< / p >
< / li >
< li >
< p > If you installed Synapse into a virtualenv, run < code > /path/to/env/bin/pip install synapse[pyjwt]< / code > to install the necessary dependencies.< / p >
< / li >
< li >
< p > For other installation mechanisms, see the documentation provided by the
maintainer.< / p >
< / li >
< / ul >
< p > To enable the JSON web token integration, you should then add an < code > jwt_config< / code > section
to your configuration file (or uncomment the < code > enabled: true< / code > line in the
existing section). See < a href = "./sample_config.yaml" > sample_config.yaml< / a > for some
sample settings.< / p >

examples below use < a href = "https://pyjwt.readthedocs.io/en/latest/" > PyJWT< / a > directly.< / p >
