OAuth2 & OpenID Connect

Simple OAuth is an implementation of the OAuth 2.0 Authorization Framework RFC. Using OAuth 2.0 Bearer Token is very easy. This project is focused in simplicity of use and flexibility. When deciding which project to use, also consider other projects like OAuth, an OAuth 1 implementation that doesn't rely on you having https in your production server.

OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0 protocol. It allows Clients to verify the identity of the End-User based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the End-User in an interoperable and REST-like manner.
