Where to learn more? Would be great if this could work with amber
Would it work as an auth service for a matrix instance?
I believe it should work with matrix.
I just went to the repo and made it public. No documentation at all, but I'm sure you can just run it by an LLM and it can tell you everything you need to know.
I originally utilized nostrband/nostr-login for the login. Since then I have developed my own login (I wanted something lighter) but have yet to deploy it to nostr-oidc-bridge.
