Duplicate: Provide a way to remove password from GitLab account

I originally set up my GitLab account using authentication via my Google account, automatically giving me 2FA.

However, logging in later, I forgot I'd done this (and the "log in with" box didn't catch my eye), so I did a password reset and added a password to my account.

This has now disabled my 2FA; anybody with that password can log in without using it. Rather than adding yet another 2FA token to the more than thirty I already have, I'd like to remove my password and continue to authenticate using Google only.
