Thanks for the quick reply. So this is a remote login. That explains why
you get the polkit prompt.
As you can see, the admin password is asked for two distinct things:
For setting a wall message and for the actual poweroff.
Both require admin privileges.
If you don't want to have the prompt for the wall message, use
systemctl poweroff --no-wall
That should only give you one polkit prompt.

Afaics, everything is working as expected, although I have to admit that
entering the credentials twice for the same command is a nuisance.

Regards,
Michael
