A new password is prompted for twice, to avoid typing mistakes. Unless the user is the superuser, the new password must have more than six characters, and must have either both upper and lower case letters, or non-letters. Some passwords which are similar to the user's name are not allowed.

No warnings are printed if the superuser chooses a poor password.
The -f and -s options are not supported.
