Currently, GoogleLogin requests two scopes when logging in or registering a new account: email and profile. The profile scope is used to get the displayName of the corresponding Google+ profile when creating an account with GoogleLogin. However, as the e-mail address is retrieved from the Google+ response, too, this requires the user to actually have a Google+ account. We could, however, get the email address from the email scope only, too, which reduces the profile permission to the displayName only. I'm not really sure, if that is enough to require the users of this extension to have a Google+ profile, or whatever is needed to get back some data with the profile scope.

The question is: What is the default MediaWiki username when we do not try to get this displayName from Google+?
