Agreed, that's not necessarily ideal. Perhaps an option to say
"use the password of X account", a kind of dummy account that
has a shell of /bin/false.

Yes, but it depends whether that user frequently uses root access. If it
only happens once a month or so, that's a whole month you'd have during
which the admin or the user could have the opportunity to detect someone
logging in unauthorized - even if it's as simple as the user noticing
"wait, I didn't actually last log in on X date...". It's certainly not
an amazing amount of security, but it's free.
