Self-Hosted Authentication Idea

[jared252016]

I would personally like to use this in a self-hosted environment, so some guides on implementing OAuth 2 without the libraries would be extremely helpful. If possible, integration with Nginx and oauth2-proxy would be beneficial for securing web applications that do not support SSO but can log you in through passed-through headers or just give you general access to the app without authenticating (for apps that have no authentication at all).

I'm not sure where you want to take Fief as far as future development goes, but to drive user growth I believe targeting the self-hosting community would substantially improve adoption rates. Many self-hosters are also admins of IAM, CTOs for startups, engineers, etc., so making it available to them to try in their home environment would be beneficial to earn their trust in enterprise environments.

Right now, there are a few OSs out there that implement this functionality already, namely Cosmos Server and Umbrel. I'd like to roll my own solution eventually and want to include Fief as an (eventually pluggable) authentication option.
