- On her computer, my wife is permanently logged into her Google account.
 - She never uses (or has used) SU.
 - I want to fix stuff on her computer and access my SU account to ask questions.
 - I always use my Google login to login to my SU account (well, I'm also permanently logged in to Google and all SE sites I use).

**How can I use my Google login to log into SU on her (Win 10) machine, without having to log her out of her Google account?**

 - I tried just logging in with my Google user/pass, but then I still get redirected to Google, where it says 'SU is asking for permission'.
 - As per [this answer](http://webapps.stackexchange.com/a/18903/55949), I tried entering http(s)://www.google.com/profiles/JanDoggen under *Other login options*/*OpenID login*, but this gives me *No OpenID endpoint found*.<br />That URL no longer seems to work, if I enter it in a browser I get redirected to https://profiles.google.com/JanDoggen with a 404 error

I would like to do this without SU/SE staff being involved. They have enough to do already ;-)
