Unfortunately we’ve had a problem with OpenID the last couple of days that caused some issues with both new registrations and signing in to existing accounts. If you have been registered for more than a week and haven’t experienced any issues then you should be fine. If you have had problems signing in the last couple of days it should work just fine now.
If you signed up during the last couple of days with Yahoo or Google OpenID there is a possibility that AlternativeTo will not recognize your OpenID login if you try to sign in now. If you experience any issues like this please send us an e-mail at firstname.lastname@example.org and we will try to solve the problem.
We’re very sorry for the inconvenience.
