<p>Account validity callbacks allow module developers to add extra steps to verify the
validity on an account, i.e. see if a user can be granted access to their account on the
Synapse instance. Account validity callbacks can be registered using the module API's
<code>register_account_validity_callbacks</code> method.</p>
<p>The available account validity callbacks are:</p>
<h3 id="is_user_expired"><a class="header" href="#is_user_expired"><code>is_user_expired</code></a></h3>
<p><em>First introduced in Synapse v1.39.0</em></p>
<pre><code class="language-python">async def is_user_expired(user: str) -&gt; Optional[bool]
</code></pre>
<p>Called when processing any authenticated request (except for logout requests). The module
can return a <code>bool</code> to indicate whether the user has expired and should be locked out of
their account, or <code>None</code> if the module wasn't able to figure it out. The user is
represented by their Matrix user ID (e.g. <code>@alice:example.com</code>).</p>
<p>If the module returns <code>True</code>, the current request will be denied with the error code
<code>ORG_MATRIX_EXPIRED_ACCOUNT</code> and the HTTP status code 403. Note that this doesn't
invalidate the user's access token.</p>
<p>If multiple modules implement this callback, they will be considered in order. If a
callback returns <code>None</code>, Synapse falls through to the next one. The value of the first
callback that does not return <code>None</code> will be used. If this happens, Synapse will not call
any of the subsequent implementations of this callback.</p>

<p>Called after successfully registering a user, in case the module needs to perform extra
operations to keep track of them. (e.g. add them to a database table). The user is
represented by their Matrix user ID.</p>
