Plasma-mobile: lightdm doesn't allow logging in

Describe your issue

What's the expected behaviour?

Being able to login with the password chosen during pmbootstrap process

What's the current behaviour?

I see: Entering my numeric password 1234 (for testing) just clears the password field when clicking login, just like any other wrong password. (Also: why no full keyboard instead of the numeric pad?)

I expect: I entered my own username during the pmbootstrap process, I expect that I first choose which user to login as by clicking my username, or at least that the lightdm greeter uses the user created by the pmbootstrap process.

How to reproduce your issue?

Run pmbootstrap, plasma-mobile, enter custom username of your choice, numeric password. Then boot the phone: numeric PIN entry is shown, doesn't accept any PIN.

What device are you using?

pine64-pinephone
