OAuth 2.0 and Bearer are RFCs now
Good news! The OAuth 2.0 Core and Bear specifications are official RFCs now:
RFC 6749 The OAuth 2.0 Authorization Framework
RFC 6750 The OAuth 2.0 Authorization Framework: Bearer Token Usage
OAuth 2.0 tokens will be used in the upcoming NimbusSSO addons that will provide OpenID Connect IdP and IdC functionality.
Dick Hardt has a nice article looking back at the history of OAuth 2.0 and its purpose.
Thanks to everyone who contributed!
