Fedora KDE setup: what is the password for "Plasma Setup"?

I installed Fedora Kinoite freshly

Apparently plasma now has an OEM style configuration where some default user gets created to then create the user.

In the initial setup the lockscreen still works, locked the screen and I cant unlock. I guess this is a bug

A forced reboot worked, but what is the password for this default user?

This has been fixed (since the Fedora 44 release) so that the unlock no longer requires a password:

I’m not sure there is a usable password for that default user, so on a system too old to have that fix, you might just need to reboot like you did.
