GoogleCL: OAuth1/AuthSub is being deprecated on April 20th, 2015. Please migrate to OAuth2 #573
Description
Over the past few years, we’ve publicized that ClientLogin, OAuth 1.0 (3LO)*,
AuthSub, and OpenID 2.0 were deprecated and would shut down on April 20, 2015.
We’re moving away from these older protocols in order to focus support on the
latest Internet standards, OAuth 2.0 and OpenID Connect, which increases
security and reduces complexity for developers.

Analysis of our logs leads us to believe that you are still using one of these
deprecated protocols. You need to ensure that your applications use our
supported authentication methods: OAuth 2.0 for API authorization or OpenID
Connect for federated authentication.
