userpasswd man page
userpasswd — A graphical tool to allow users to change their passwords.
userpasswd [ options ]
userpasswd is a graphical tool to allow users to easily change their passwords. Aside from being a nice GUI frontend, this program does the right thing when the pam configuration has changed.
This program has no command line options of its own, but it does take the standard X program options like -display and such. See the X(1) man page for some of the common options.
No known bugs, but compatibility with bizarre changes in the pam configuration have not been tested aggressively. If you have a non-standard pam configuration, I'd be interested to hear whether it worked and what kind of configuration you have.
