After joining Google+, the profiles.google.com/username URL redirects to plus.google.com/[long number]/posts. When trying to log in on SO using the profiles.google.com URL, I got (line breaks for clarity):

Unable to log in with your OpenID provider:

  • Shouldn't you simply click on the google button?

  • @Kobi: Hm. Well, that did work but I have both my google account openid and my google profile openid associated with my SE accounts. Last I knew those were separate, so if I hadn't also had the account openid associated it wouldn't have worked. I seem to recall the main google openid provider being undesirable for some reason a while back, so I'd been using the profile version since then. Maybe that isn't the case anymore.

  • same thing happening to me. used my alternate login and removed my google profiles and added myopenid back. Commented Jun 30, 2011 at 19:45
  • You also must have your profile Public for it to work anymore.

  • There is also something different I got: When I typed my Google+ URL, I was redirected to my Google Profile URL. Because of that, I can't get in to Google+. Really, this is confusing. Commented Jul 2, 2011 at 12:24

    I hope they change this, google seems to completely miss the point of OpenIDs and how they're actually used in the real world. A provider repeatedly breaking endpoints isn't a provider, they're actively doing more harm than good. Commented Jul 9, 2011 at 11:47
  • So what do those of us that now have google+ do?

  • @M. Tibbits: I'm just using the normal Google (non-profile) OpenID now. Not sure what you should do if you're using the profile as your main login and don't have an alternate.

It appears that signing up for Google+ breaks Google Profile OpenIDs.

There's not much we can do from our end, as there's no obvious connection between the old and new identifiers.

If you intend to signup for Google+, you should use a different OpenID provider than Google Profiles. If you're already locked out, create a new account using the top-level Google login; it should be auto-merged with your existing Google Profile backed account, giving you an alternate OpenID to login with (after which, you should delete the Google Profile OpenID).

If you're still having issues, e-mail us using the contact link with the details; preferably from the Gmail account associated with your Google Profile.


I think existing users can log-in using the standard Google. If it wasn't their alternate, and they are asked to "create a new account" they can hit cancel, but since they are now authenticated with Google, it still works, so it will detect that they are logged in. That happened on a few sites where my only login was my Google profile's login.

  • This has worked for me, thanks for the tip!

in Api Console replace your redirect urls to http and remove https and You can also use 'scope': 'https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/userinfo.email' . This solution worked for me.
