OpenID Connect (OIDC)

Abstract

OpenID Connect provides a lightweight framework for identity interactions in a RESTful manner and was ratified as a standard by its membership on February 26, 2014. It was developed under the OpenID Foundation and has its roots in OpenID, but was greatly affected by OAuth 2.0. OpenID Connect is the most popular Identity Federation protocol at the time of this writing. Most of the applications developed in the last three years are supporting OpenID Connect. Ninety-two percent of the 8 billion+ authentication requests Microsoft Azure AD handled in May 2018 were from OpenID Connect--enabled applications.
