I recently started to read up on OAuth2, and just now noticed how many extensions exist to this protocol. Is there an overview or some kind of a map of OAuth2 and all of its (official) extensions? I was hoping that something like in the diagram below somewhere existed.
If no such document exists, then I would like to know which official OAuth2 extensions there are. I could only find an official site for OAuth1 extensions.
I know of the following extensions:
- The OAuth 2.0 Authorization Framework: Bearer Token Usage
- OAuth Assertion Framework
- OAuth JWT Assertion Profiles
- OpenID Connect protocol suite
- SAML 2.0 Profile for OAuth2.0 Client Authentication and Authorization Grants
