This is an old topic, but this comes up first on search results. It is possible to some degree with this plugin now:
How to get user's (has logged in) uid or email?
I found that sso-github and sso-google are using email what comes from oauth api.
However,This API can't get email address.so,I can't let this plugin use profiles to bind user.
Could you tell me whether some apis is exist(e.g. if you logged in,you can get your email or uid).
This API can't provide user's email.
Like PHP BBS,it will provide a variable to save user's profile(include uid,email).
I want to know how to get user's (has logged in) uid or email.
You'll want to use a registration interstitial, which sso-facebook uses.
@julian but,how to solve the bind problem
Thanks a lot.
Maybe this can be useful:
Twitter doesn't expose email addresses either, and we also have logic to link your existing account to it as well.
