This process is known as '3pid verification'. ('3pid', or 'threepid', -stands for third-party identifier, and we use it to refer to external -identifiers such as email addresses and phone numbers.)</p> -<p>Previous versions of Synapse delegated the task of 3pid verification to an -identity server by default.

Instead, -the server administrator will need to explicitly decide how they would like the -verification messages to be sent.</p> -<p>In the medium term, the <code>vector.im</code> and <code>matrix.org</code> identity servers will -disable support for delegated 3pid verification entirely. However, in order to -ease the transition, they will retain the capability for a limited -period. Delegated email verification will be disabled on Monday 2nd December -2019 (giving roughly 2 months notice). Disabling delegated SMS verification -will follow some time after that once SMS verification support lands in -Synapse.</p> -<p>Once delegated 3pid verification support has been disabled in the <code>vector.im</code> and -<code>matrix.org</code> identity servers, all Synapse versions that depend on those -instances will be unable to verify email and phone numbers through them.

Support for -delegated email verification will be disabled on Monday 2nd December. - -The ``account_threepid_delegates`` dictionary defines whether the homeserver -should delegate an external server (typically an `identity server -<https://matrix.org/docs/spec/identity_service/r0.2.1>`_) to handle sending -confirmation messages via email and SMS. - -So to delegate email verification, in ``homeserver.yaml``, set -``account_threepid_delegates.email`` to the base URL of an identity server. For -example: - -.. code:: yaml - - account_threepid_delegates: - email: https://example.com # Delegate email sending to example.com - -Note that ``account_threepid_delegates.email`` replaces the deprecated -``email.trust_identity_server_for_password_resets``: if -``email.trust_identity_server_for_password_resets`` is set to ``true``, and -``account_threepid_delegates.email`` is not set, then the first entry in -``trusted_third_party_id_servers`` will be used as the -``account_threepid_delegate`` for email. This is to ensure compatibility with -existing Synapse installs that set up external server handling for these tasks -before v1.4.0. If ``email.trust_identity_server_for_password_resets`` is -``true`` and no trusted identity server domains are configured, Synapse will -report an error and refuse to start. - -If ``email.trust_identity_server_for_password_resets`` is ``false`` or absent -and no ``email`` delegate is configured in ``account_threepid_delegates``, -then Synapse will send email verification messages itself, using the configured -SMTP server (see above). -that type. - -Phone numbers -</code></pre> -<p>Synapse does not support phone-number verification itself, so the only way to -maintain the ability for users to add phone numbers to their accounts will be -by continuing to delegate phone number verification to the <code>matrix.org</code> and -<code>vector.im</code> identity servers (or another identity server that supports SMS -sending).</p> -<p>The <code>account_threepid_delegates</code> dictionary defines whether the homeserver -should delegate an external server (typically an <code>identity server <https://matrix.org/docs/spec/identity_service/r0.2.1></code>_) to handle sending -confirmation messages via email and SMS.</p> -<p>So to delegate phone number verification, in <code>homeserver.yaml</code>, set -<code>account_threepid_delegates.msisdn</code> to the base URL of an identity -server.

Once done you can run the home server using::</p> -<pre><code>$ python synapse/app/homeserver.py --config-path homeserver.config -</code></pre> -<p>See the README.rst for more information.</p> -<p>Also note that some config options have been renamed, including:</p> -<ul> -<li>"host" to "server-name"</li> -<li>"database" to "database-path"</li> -<li>"port" to "bind-port" and "unsecure-port"</li> -</ul> -<h1 id="upgrading-to-v001"><a class="header" href="#upgrading-to-v001">Upgrading to v0.0.1</a></h1> -<p>This release completely changes the database schema and so requires upgrading -it before starting the new version of the homeserver.</p> -<p>The script "database-prepare-for-0.0.1.sh" should be used to upgrade the -database. This will save all user information, such as logins and profiles, -but will otherwise purge the database. This includes messages, which -rooms the home server was a member of and room alias mappings.</p> -<p>Before running the command the homeserver should be first completely -shutdown. To run it, simply specify the location of the database, e.g.:</p> -<p>./scripts/database-prepare-for-0.0.1.sh "homeserver.db"</p> -<p>Once this has successfully completed it will be safe to restart the -homeserver. You may notice that the homeserver takes a few seconds longer to -restart than usual as it reinitializes the database.</p> -<p>On startup of the new version, users can either rejoin remote rooms using room -aliases or by being reinvited. Alternatively, if any other homeserver sends a -message to a room that the homeserver was previously in the local HS will -automatically rejoin the room.</p> - - </main> - - <nav class="nav-wrapper" aria-label="Page navigation"> - <!-- Mobile navigation buttons --> - - <a rel="prev" href="../delegate.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="../MSC1711_certificates_FAQ.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="../delegate.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="../MSC1711_certificates_FAQ.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> \ No newline at end of file |
