Build an OIDC provider with rodauth-oauth in rails, while keeping your authentication · HTTPX

I’ve written before about rodauth-oauth and how to use it to make an OAuth2 or OIDC Connect provider out of a rails application, and where I built a rails demo app based out of Janko Mahronic’s rodauth-rails demo app as a workable tutorial. It shows well what rodauth accomplishes, how integrating it in a rails app became significantly simpler thanks to rodauth-rails, and how one can building an OAuth/OIDC provider using rodauth-oauth on top of that.Recently, I got asked by a former co-worker what do I suggest for building an OAuth provider in a rails app. I suggested rodauth-oauth. “But we already have our own authentication. Doesn’t rodauth-oauth require that authentication is handled by rodauth?”.
