<p>Synapse supports multiple methods of authenticating users, either out-of-the-box or through custom pluggable
authentication modules.</p>
<p>Included in Synapse is support for authenticating users via:</p>
<ul>
<li>A username and password.</li>
<li>An email address and password.</li>
<li>Single Sign-On through the SAML, Open ID Connect or CAS protocols.</li>
<li>JSON Web Tokens.</li>
<li>An administrator's shared secret.</li>
</ul>
<p>Synapse can additionally be extended to support custom authentication schemes through optional &quot;password auth provider&quot;
modules.</p>
