FYI!!! In case you start getting re-directed to porn sites.
Maybe the admin got hacked?
edit: lemmy.blahaj.zone has also been hacked. beehaw.org is also down, possibly intentionally by their admins until the issue is fixed.

Yeah, the Lemmy 2FA implementation sucks. It only works in certain authenticators - Authy not being one of them. Google Authenticator does work and apparently so does the iOS keychain (but can’t confirm that one).
Best way to do it is to enable it and set it up but keep the settings window open, then open a separate incognito window and try to log in. If your 2FA code doesn’t work, go back to the other settings window and disable it.
I am using 2fas with no issue and set it up using the method you described. So far, so good…in case anyone needed a vote of confidence!
