When the server upgraded to 0.19.0 and everyone's 2FA was reset, I again setup my 2FA. It accepted my code and 2FA was enabled. I tried to login again but it said multiple times that the code generated by the app was invalid. I try to disable this multi factor authentication but even that won't work since it asks for the TOTP code which it marks as invalid. How is a TOTP code generated by Lemmy's link and accepted by it's servers to validate 2FA in the first place be invalid?
I am effectively now logged out from this account of mine because I can't sign into a new session and if I logout of this session, then boom, this account of mine is as good as dead.
I have the same problem. TOTP is on, but the generated code is always reported as incorrect.
After resetting it (thank you, Milan) it seems to work now. No idea what the issue was...
