> the MOK dialog password is your systems root password.

Thanks. I tried the root password too and it didn't work. A possible reason are
the special characters in my password, I have no idea if the unexpected blue
enrollment screen demanding an unspecified password expects a US keyboard, I
can't see what I type either since it only shows asterisks and there is no
shell to type in and see if special characters are correct or what the
equivalent key is. 

Also it isn't specified anywhere that it's the root password, are end users
really expected to guess this? Is this really the desired design for openSUSE?
I ask this after spending many hours months ago until I figured out why
Virtualbox did no longer work after a fresh openSUSE 15.3 install, and after
searching for the cause I see many other users had the same problem..
