how to connect the google-account with my site?
Sign in with Google account using OAuth2.0 which is clearly explained
A system to quick login with Google account using OpenID authentication: http://www.9lessons.info/2011/07/login-with-google-account.html
While not really covering Google auth, I’ve found this article very useful when building openid authentication for my website.
