Dear Maintainer,

I booted the debian bookworm live system from an USB disk. I did some things
with it, and left it alone for a while. When I came back some time later,
the screen had been locked and the system asked for the password to unlock it.

However, the live system does not set a password for the default user. There
was no way to unlock the screen that I could figure out. Virtual consoles
do not help as logging in them again requires the password.

I have at least two ways to get around this problem, but I think this should
be fixed. For these workarounds, they need to be done after starting the
live image but before the screen becomes locked.

The first workaround: use `passwd` to set a password for the default user.
In this way there is now a known password which can be used.

The second workaround: disable the screen lock from the configuration.
In this way the screen is never locked.

My expectation is that I can boot the live image and then use it without
worrying if it becomes permamently locked.
