Q. What is the difference between authentication type OAUTH and OpenID?
A. When you start from scratch then you probably want OAUTH. When you've used non-SSO OpenID and need Google OAuth provider support after OpenID service shutdown, then you need Hybrid OpenID+OAuth authentication method. This is supported with auth.type = 'OpenID'.
Q. Why linking of user identity from old Google's OpenID account to new OAuth account doesn't work for my site?
