Introducing CentralLogin, an OpenID Connect Provider

This app builds on the foundations of the Doorkeeper, Doorkeeper::OpenidConnect and Devise to provide a central login system.

While Doorkeeper supports other OAuth flows, CentralLogin focusses on OpenID Connect as it is a more complete, and hence useful standard, for most use cases where you want to support authentication & authorization.

This project builds on years of juggling with different authentication providers and implementations. It may cut corners to be a pragmatic and less flexible solution which you can host on your own. You don’t have to tie your users to a closed authentication system such as Auth0, Azure Directory, Cognito (the horror, really, stay away from it) or something else. In the past I’ve been a happy user of Keycloak, which is definitely way more advanced than this project, but it in the end it is a Java application and hence harder for me to maintain and not focussed on what I think are the core requirements :)

So, are you in the market for:

• an open source solution for authentication & authorisation;
• a solution that you can understand;
• allows for simple role / resource mapping using groups;
• that has understandable amount of bells and whistles?

Then CentralLogin might be for you :)
