There are a few options for that:</p> +<ul> +<li> +<p>start a local OP. Synapse has been tested with <a href="https://www.ory.sh/docs/hydra/">Hydra</a> and +<a href="https://github.com/dexidp/dex">Dex</a>. Note that for an OP to work, it should be served under a +secure (HTTPS) origin. A certificate signed with a self-signed, locally +trusted CA should work. In that case, start Synapse with a <code>SSL_CERT_FILE</code> +environment variable set to the path of the CA.</p> +</li> +<li> +<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 +<a href="https://www.okta.com/">Okta</a>.
