  150. <p>Synapse can be configured to use an OpenID Connect Provider (OP) for
  151. authentication, instead of its own local password database.</p>
  152. <p>Any OP should work with Synapse, as long as it supports the authorization code
  153. flow. There are a few options for that:</p>
  154. <ul>
  155. <li>
  156. <p>start a local OP. Synapse has been tested with <a href="https://www.ory.sh/docs/hydra/">Hydra</a> and
  157. <a href="https://github.com/dexidp/dex">Dex</a>. Note that for an OP to work, it should be served under a
  158. secure (HTTPS) origin. A certificate signed with a self-signed, locally
  159. trusted CA should work. In that case, start Synapse with a <code>SSL_CERT_FILE</code>
  160. environment variable set to the path of the CA.</p>
  161. </li>
  162. <li>
  163. <p>set up a SaaS OP, like <a href="https://developers.google.com/identity/protocols/oauth2/openid-connect">Google</a>, <a href="https://auth0.com/">Auth0</a> or
  164. <a href="https://www.okta.com/">Okta</a>. Synapse has been tested with Auth0 and Google.</p>
  165. </li>
  166. </ul>
  167. <p>It may also be possible to use other OAuth2 providers which provide the
  168. <a href="https://tools.ietf.org/html/rfc6749#section-4.1">authorization code grant type</a>,
  169. such as <a href="https://developer.github.com/apps/building-oauth-apps/authorizing-oauth-apps">Github</a>.</p>
  170. <h2 id="preparing-synapse"><a class="header" href="#preparing-synapse">Preparing Synapse</a></h2>
  171. <p>The OpenID integration in Synapse uses the
  172. <a href="https://pypi.org/project/Authlib/"><code>authlib</code></a> library, which must be installed
  173. as follows:</p>
  174. <ul>
  175. <li>
  176. <p>The relevant libraries are included in the Docker images and Debian packages
  177. provided by <code>matrix.org</code> so no further action is needed.</p>
  178. </li>
  179. <li>
  180. <p>If you installed Synapse into a virtualenv, run <code>/path/to/env/bin/pip install matrix-synapse[oidc]</code> to install the necessary dependencies.</p>
  181. </li>
  182. <li>
  183. <p>For other installation mechanisms, see the documentation provided by the
  184. maintainer.</p>
  185. </li>
  186. </ul>
  187. <p>To enable the OpenID integration, you should then add a section to the <code>oidc_providers</code>
  188. setting in your configuration file.
  189. See the <a href="usage/configuration/config_documentation.html#oidc_providers">configuration manual</a> for some sample settings, as well as
  190. the text below for example configurations for specific providers.</p>
  191. <h2 id="sample-configs"><a class="header" href="#sample-configs">Sample configs</a></h2>
  192. <p>Here are a few configs for providers that should work with Synapse.</p>
  193. <h3 id="microsoft-azure-active-directory"><a class="header" href="#microsoft-azure-active-directory">Microsoft Azure Active Directory</a></h3>
  194. <p>Azure AD can act as an OpenID Connect Provider. Register a new application under
  195. <em>App registrations</em> in the Azure AD management console. The RedirectURI for your
  196. application should point to your matrix server:
  197. <code>[synapse public baseurl]/_synapse/client/oidc/callback</code></p>
  198. <p>Go to <em>Certificates &amp; secrets</em> and register a new client secret. Make note of your
  199. Directory (tenant) ID as it will be used in the Azure links.
  200. Edit your Synapse config file and change the <code>oidc_config</code> section:</p>
