Documentation incorrectly suggests people need Google Authenticator (and account) for 2FA
Many of our users are open source contributors (on https://gitlab.common-lisp.net). Many don't want to open Google accounts in order to log in using 2FA -- yet we want to require 2FA in order to raise the bar on passwords.
The GitLab documentation page currently suggests to our users that they need a Google Account to get 2FA for our site: https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/profiles/two_factor_auths/show.html.haml#L28 says to download from Play Store.
However, FreeOTP from f-droid is sufficient for 2FA purposes.
