Are there any authentication platforms as a service that have functionality like okta/Auth0?<p>It would be pretty easy (but a lot of work) to roll your own using Django. Is there anything that works out of the box? and is battle tested?
Getting authentication and federation "right" is tough, and I wouldn't recommend implementing it yourself.<p>I would consider looking into Keycloak, which is an opensource platform similar to Okta/Auth0 that you can self host:<p><a href="https://www.keycloak.org/" rel="nofollow">https://www.keycloak.org/</a>
