Any way to make bitwarden work on pw form appearing after username

I am a student trying to use the University Management plattform OLAT specifically this one:

It used to work fine and Firefox integrated autofill also still works but Bitwarden cant seem to fill the pw field. I also tried custom fields couldnt get it to work. as Usename you can try stu222000 or any stu****** .

Any ideas? I think bitwarden doesnt even detect the field because its not existant before you put in a usename.

@FeKgr Welcome to the forum!

The automatic auto-fill (“Auto-fill on page load”) may not work (for reasons you have stated), but you can use the keyboard shortcut Ctrl+Shift+L to auto-fill this form (first on the username screen, and then again at the password prompt).
