I had 2FA enabled for lemmy.world before the big update this past weekend, and when I logged out/in this morning I discovered that 2FA had been turned off for my account. I’ve got it turned back on and I think it’s working now, but just a heads up that if you had 2FA enabled you might need to re-enable it.
Odd, I remember reading it in that post but you’re correct it’s not there.
