OpenID 2.0 for Google Accounts is going away in April 2015

What is OpenID Connect?

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.

OpenID Connect allows clients of all types, including Web-based, mobile, and JavaScript clients, to request and receive information about authenticated sessions and end-users. The specification suite is extensible, allowing participants to use optional features such as encryption of identity data, discovery of OpenID Providers, and session management, when it makes sense for them.

OpenID 2.0 (Migration)

Google has deprecated OpenID 2.0 and will shut it down after a migration period. If your app uses OpenID 2.0, the userinfo endpoint, or OAuth 2.0 login (early version), you should migrate your app by the deadlines given in the migration timetable.

If you are looking for documentation for web applications that use the deprecated OpenID 2.0 for Google login, see OpenID 2.0 (Deprecated). For information about using the deprecated OpenID 2.0 authentication with Google Apps (hosted) accounts, see OpenID API for Google Apps accounts (Deprecated).
