Additionally, here is a list of known password auth provider module implementations:</p> <ul> <li><a href="https://github.com/matrix-org/matrix-synapse-ldap3/">matrix-synapse-ldap3</a></li> <li><a href="https://github.com/devture/matrix-synapse-shared-secret-auth">matrix-synapse-shared-secret-auth</a></li> <li><a href="https://github.com/ma1uta/matrix-synapse-rest-password-provider">matrix-synapse-rest-password-provider</a></li> </ul> <h2 id="required-methods"><a class="header" href="#required-methods">Required methods</a></h2> <p>Password auth provider classes must provide the following methods:</p> <ul> <li> <p><code>parse_config(config)</code> This method is passed the <code>config</code> object for this module from the homeserver configuration file.</p> <p>It should perform any appropriate sanity checks on the provided configuration, and return an object which is then passed into <code>__init__</code>.</p> <p>This method should have the <code>@staticmethod</code> decoration.</p> </li> <li> <p><code>__init__(self, config, account_handler)</code></p> <p>The constructor is passed the config object returned by <code>parse_config</code>, and a <code>synapse.module_api.ModuleApi</code> object which allows the password provider to check if accounts exist and/or create new ones.</p> </li> </ul> <h2 id="optional-methods"><a class="header" href="#optional-methods">Optional methods</a></h2> <p>Password auth provider classes may optionally provide the following methods:</p> <ul> <li> <p><code>get_db_schema_files(self)</code></p> <p>This method, if implemented, should return an Iterable of <code>(name, stream)</code> pairs of database schema files. Each file is applied in turn at initialisation, and a record is then made in the database so that it is not re-applied on the next start.</p> </li> <li> <p><code>get_supported_login_types(self)</code></p> <p>This method, if implemented, should return a <code>dict</code> mapping from a login type identifier (such as <code>m.login.password</code>) to an iterable giving the fields which must be provided by the user in the submission to <a href="https://matrix.org/docs/spec/client_server/latest#post-matrix-client-r0-login">the <code>/login</code> API</a>. These fields are passed in the <code>login_dict</code> dictionary to <code>check_auth</code>.</p> <p>For example, if a password auth provider wants to implement a custom login type of <code>com.example.custom_login</code>, where the client is expected to pass the fields <code>secret1</code> and <code>secret2</code>, the provider should implement this method and return the following dict:</p> <pre><code class="language-python">{"com.example.custom_login": ("secret1", "secret2")} </code></pre> </li> <li> <p><code>check_auth(self, username, login_type, login_dict)</code></p> <p>This method does the real work. If implemented, it will be called for each login attempt where the login type matches one of the keys returned by <code>get_supported_login_types</code>.</p> <p>It is passed the (possibly unqualified) <code>user</code> field provided by the client, the login type, and a dictionary of login secrets passed by the client.</p> <p>The method should return an <code>Awaitable</code> object, which resolves to the canonical <code>@localpart:domain</code> user ID if authentication is successful, and <code>None</code> if not.</p> <p>Alternatively, the <code>Awaitable</code> can resolve to a <code>(str, func)</code> tuple, in which case the second field is a callback which will be called with the result from the <code>/login</code> call (including <code>access_token</code>, <code>device_id</code>, etc.)</p> </li> <li> <p><code>check_3pid_auth(self, medium, address, password)</code></p> <p>This method, if implemented, is called when a user attempts to register or log in with a third party identifier, such as email. It is passed the medium (ex. "email"), an address (ex. "<a href="mailto:jdoe@example.com">jdoe@example.com</a>") and the user's password.</p> <p>The method should return an <code>Awaitable</code> object, which resolves to a <code>str</code> containing the user's (canonical) User id if authentication was successful, and <code>None</code> if not.</p> <p>As with <code>check_auth</code>, the <code>Awaitable</code> may alternatively resolve to a <code>(user_id, callback)</code> tuple.</p> </li> <li> <p><code>check_password(self, user_id, password)</code></p> <p>This method provides a simpler interface than <code>get_supported_login_types</code> and <code>check_auth</code> for password auth providers that just want to provide a mechanism for validating <code>m.login.password</code> logins.</p> <p>If implemented, it will be called to check logins with an <code>m.login.password</code> login type. It is passed a qualified <code>@localpart:domain</code> user id, and the password provided by the user.</p> <p>The method should return an <code>Awaitable</code> object, which resolves to <code>True</code> if authentication is successful, and <code>False</code> if not.</p> </li> <li> <p><code>on_logged_out(self, user_id, device_id, access_token)</code></p> <p>This method, if implemented, is called when a user logs out. It is passed the qualified user ID, the ID of the deactivated device (if any: access tokens are occasionally created without an associated device ID), and the (now deactivated) access token.</p> <p>It may return an <code>Awaitable</code> object; the logout request will wait for the <code>Awaitable</code> to complete, but the result is ignored.</p> </li> </ul> </main> <nav class="nav-wrapper" aria-label="Page navigation"> <!-- Mobile navigation buttons --> <a rel="prev" href="sso_mapping_providers.html" class="mobile-nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> <i class="fa fa-angle-left"></i> </a> <a rel="next" href="jwt.html" class="mobile-nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> <i class="fa fa-angle-right"></i> </a> <div style="clear: both"></div> </nav> </div> </div> <nav class="nav-wide-wrapper" aria-label="Page navigation"> <a rel="prev" href="sso_mapping_providers.html" class="nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> <i class="fa fa-angle-left"></i> </a> <a rel="next" href="jwt.html" class="nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> <i class="fa fa-angle-right"></i> </a> </nav> </div> <script type="text/javascript"> window.playground_copyable = true; </script> <script src="elasticlunr.min.js" type="text/javascript" charset="utf-8"></script> <script src="mark.min.js" type="text/javascript" charset="utf-8"></script> <script src="searcher.js" type="text/javascript" charset="utf-8"></script> <script src="clipboard.min.js" type="text/javascript" charset="utf-8"></script> <script src="highlight.js" type="text/javascript" charset="utf-8"></script> <script src="book.js" type="text/javascript" charset="utf-8"></script> <!-- Custom JS scripts --> <script type="text/javascript" src="docs/website_files/table-of-contents.js"></script> </body> </html>
