User Authentication

Synapse supports multiple methods of authenticating users, either out-of-the-box or through custom pluggable authentication modules.

Included in Synapse is support for authenticating users via:

• A username and password.
• An email address and password.
• Single Sign-On through the SAML, Open ID Connect or CAS protocols.
• JSON Web Tokens.
• An administrator's shared secret.

Synapse can additionally be extended to support custom authentication schemes through optional "password auth provider" modules.
