+<h2 id="authenticate-as-a-server-admin"><a class="header" href="#authenticate-as-a-server-admin">Authenticate as a server admin</a></h2>
+<p>Many of the API calls in the admin api will require an <code>access_token</code> for a
+server admin. (Note that a server admin is distinct from a room admin.)</p>
+<p>A user can be marked as a server admin by updating the database directly, e.g.:</p>
+<pre><code class="language-sql">UPDATE users SET admin = 1 WHERE name = '@foo:bar.com';
+</code></pre>
+<p>A new server admin user can also be created using the <code>register_new_matrix_user</code>
+command. This is a script that is located in the <code>scripts/</code> directory, or possibly
+already on your <code>$PATH</code> depending on how Synapse was installed.</p>
+<p>Finding your user's <code>access_token</code> is client-dependent, but will usually be shown in the client's settings.</p>
+<h2 id="making-an-admin-api-request"><a class="header" href="#making-an-admin-api-request">Making an Admin API request</a></h2>
+<p>Once you have your <code>access_token</code>, you will need to authenticate each request to an Admin API endpoint by
+providing the token as either a query parameter or a request header. To add it as a request header in cURL:</p>
+<pre><code class="language-sh">curl --header &quot;Authorization: Bearer &lt;access_token&gt;&quot; &lt;the_rest_of_your_API_request&gt;
+</code></pre>
+<p>For more details on access tokens in Matrix, please refer to the complete
+<a href="https://matrix.org/docs/spec/client_server/r0.6.1#using-access-tokens">matrix spec documentation</a>.</p>

+## Modules ##
+
+# Server admins can expand Synapse's functionality with external modules.
+#
+# See https://matrix-org.github.io/synapse/develop/modules.html for more
+# documentation on how to configure or create custom modules for Synapse.
+#
+modules:
+    # - module: my_super_module.MySuperClass

+    #       do_thing: true
+    # - module: my_other_super_module.SomeClass

+
+## 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://github.com/matrix-org/synapse/blob/master/docs/delegate.md
+# 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 /_matrix/client will redirect
+# to if 'webclient' is configured under the 'listeners' configuration.
+#
+# This option can be also set to the filesystem path to the web client

+# under the 'listeners' configuration, however this is a security risk:

+
+# 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

+#
+#   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:

+#
+#       compress: set to true to enable HTTP compression for this resource.
+#
+#   additional_resources: Only valid for an 'http' listener. A map of

+#
+# Valid resource names are:

+#
+# 'limit_usage_by_mau' disables/enables monthly active user blocking. When
+# enabled and a limit is reached the server returns a 'ResourceLimitError'

+#
+# 'max_mau_value' is the hard limit of monthly active users above which

+#
+# 'mau_trial_days' is a means to add a grace period for active users. It

+# 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

+#
+# If this feature is enabled, Synapse will regularly look for and purge events

+  #default_policy:
+  #  min_lifetime: 1d

+
+  # 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).

+  # 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

+## Database ##
+
+# The 'database' setting defines the database that synapse uses to store all of

+#
+# 'name' gives the database engine to use: either 'sqlite3' (for SQLite) or

+
+## 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 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.

+# 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.

+
+# 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;

+## 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:

+#   * password_config.enabled
+#
+# You will also want to investigate the settings under the &quot;sso&quot; configuration
+# section below.

+#       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. Valid values are: 'auto' or 'userinfo_endpoint'.
+#
+#       Defaults to 'auto', which fetches the userinfo endpoint if 'openid' is
+#       included in 'scopes'. Set to 'userinfo_endpoint' to always fetch 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://github.com/matrix-org/synapse/blob/master/docs/sso_mapping_providers.md#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://github.com/matrix-org/synapse/blob/master/docs/openid.md
+# for information on how to configure these options.
+#
+# For backwards compatibility, it is also possible to configure a single OIDC
+# provider via an 'oidc_config' setting. This is now deprecated and admins are
+# advised to migrate to the 'oidc_providers' format. (When doing that migration,
+# use 'oidc' for the idp_id to ensure that existing users continue to be
+# recognised.)
+#
+oidc_providers:
