I cannot connect with my Google account because I have an accent in my first name. And I cannot create an account with just my email (it sais "user not found")
I just gave up trying to connect it to Google or Twitter since those don't work. I ended up using the email signup option but neither signing up nor logging in happen over HTTPS.
That's why authentication through reliable big services like Google is a thing guys. At least they get it right.
Seriously. I just get a blank Google+ popup after authenticating. When I close the dialog it says it couldn't authenticate. Oh well. Looked like a cool idea.
