AuthSub for Google Accounts is going away
Some applications and websites use AuthSub for authentication when you're signing in, and to access data that you've given them permission to access. AuthSub has been superseded by OAuth 2.0. Starting April 20, 2015, AuthSub will no longer work for Google Accounts.
If you've seen a warning that's brought you to this page, it means that you're using an application or website with AuthSub and may be affected by this change. For more information, we recommend you visit that application's help center, or contact its support team.
If you're a developer of an application that uses AuthSub, please migrate to OAuth 2.0 by the shutdown date. Learn how to migrate to OAuth 2.0, and about the AuthSub end of life schedule.
