When using YubiKey for example, the laucher ask login when starting the first session.
Afther filling in the username and password it ask for the YubiKey.
But you need to click in the input field to focus it and the yubikey code is displayed as text instead of as as password field.
I think it is faster to login if the autofocus is correct.
I will look into this. You're absolutely right, it's faster and clearly how the Yubikey usually works elsewhere!
