The document provides an overview of OpenID Connect, a new standard for identity that is based on OAuth 2.0. It discusses how OpenID Connect allows clients to authenticate users through an authorization server without having to handle usernames and passwords. The document outlines the basic OpenID Connect workflow which involves the client obtaining an ID token from the authorization server after the user authenticates. This ID token contains claims about the user that are verified by the authorization server's signature. The document encourages developers to leverage OpenID Connect to build applications that can acquire customers through social sign-on and to rapidly develop secure mobile apps.
