OAuth 3
OAuth 3 does not exist. However, there are two independent efforts to continue to evolve OAuth 2.0.
- OAuth 2.1, an officially adopted effort by the OAuth Working Group to consolidate and simplify the best practices of OAuth 2.0.
- GNAP, a new IETF Working Group to develop a next-generation protocol that encompasses many use cases that are challenging to implement with OAuth 2.0.
