After installing the app, have you activated it for your user account and linked to a TOTP app? Here you will find screenshots how the settings dialog looks like:

I think there are different ways to get access to your system again:

  1. Use your normal credentials to login.

  2. Use a backup code to login.

thank you @j-ed , I will go through it again and double-check everything. The strange thing is it’s “random” when it happens. Sometimes I get the usual (enter your code) screen, others I get the above screen, so I have to guess that I did get it setup right and something is going awry sometimes.

I’ve been using the backup codes up until now, but I’m down to my last code now, and then I’ll have to regenerate a whole new set of backup codes.

I’ve personally never had problems using the different 2fa apps in the past. As long as you follow the required setup steps, everything should work as expected.
