Code:

root@:~/bin# gpasswd
Usage: gpasswd [option] GROUP

Options:
  -a, --add USER                add USER to GROUP
  -d, --delete USER             remove USER from GROUP
  -h, --help                    display this help message and exit
  -Q, --root CHROOT_DIR         directory to chroot into
  -r, --remove-password         remove the GROUP's password
  -R, --restrict                restrict access to GROUP to its members
  -M, --members USER,...        set the list of members of GROUP
  -A, --administrators ADMIN,...
                                set the list of administrators for GROUP
Except for the -A and -M options, the options cannot be combined.

Normally groups are used to offer some common permissions, either file based or role based part of the OS.

One doesn't normally allow some user to convert their permissions with a password. It usually is the task for an admin or power user of some sort.

I have seen some cases where an authenticated user could access some web site or other app that would authenticate their level by some second means to do some task.

It may be possible to allow some users a sudo task that would allow them to change groups. You'd have to construct the script or task and the sudo permissions pretty well. I'd still assume they'd have a way around it.

What exactly do you want to do with this?
