OpenID Connect  OpenID Connect (OIDC) is an authentication layer on top of OAuth 2.0, an authorization framework. The standard is controlled by the OpenID Foundation. OpenID Connect is a simple identity layer on top of the OAuth 2.0 protocol, which allows computing clients to verify the identity of an 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.
