2FA
(lemmy.ca)
From posts in other subs it seems like Lemmy 2fa is just sort of buggy in general right now. I've seen several subs with sticky posts recommending not using it yet. I'd choose a strong random password and wait a few weeks and see how it shakes out, keep an eye on server announcements and Lemmy release notes for updates.
Worked for me... entered the credentials, got the 2FA pop up. On Android.
