OpenID with Google account: now impossible to connect properly

How to setup my account with OpenID, it always fails. I have two email addresses but apparently they were mixed on this help, where I'm logged in with my Google+ account. But it's impossible to setup the OpenID for Google, and there's a mix now with my account on OSM which is not based on Google account. Why is'nt there a "GoogleConnect" to correctly setup and secure the login ? The old method based on OpenID2 is no longer working without the OAuth2 method. So I can no longner login correctly here without requesting each tim a new temporary access token by email. Basic OpenID is no logner working with Google which requires stronger methods (buyt which is still conforming with the OpenID standard, that this help site supports only with an outdated specification). As well I can no connect using a Blogger account (same reason): there are missing tokens that this help site does not record properly. Could you add GoogleConnect as a method (and then drop your "Blogger" method that is no longer working at all)?
