NAME
       lchage - Display or change user password policy

SYNOPSIS
       lchage [OPTION]... user

DESCRIPTION
       Displays or allows changing password policy of user.

OPTIONS
       -d, --date=days
              Set the date of last password change to days after Jan 1 1970.
              Set  days  to  -1 to disable password expiration (i.e. to ignore
              --mindays, and --maxdays and related settings).
              Set days to 0 to enforce password change on next  login.   (This
              also   disables   password  expiration  until  the  password  is
              changed.)

       -E, --expire=days
              Set the account expiration date to days after Jan 1  1970.   Set
              days to -1 to disable account expiration.

       -i, --interactive
              Ask  all questions when connecting to the user database, even if
              default answers are set up in libuser configuration.

       -I, --inactive=days
              Disable the account after days after password expires (after the
              user  is  required  to  change the password).  Set days to -1 to
              keep the account enabled indefinitely after password expiration.

       -l, --list
              Only list current user's policy and make no changes.

       -m, --mindays=days
              Require at least days days between password changes.   Set  days
              to 0 or -1 to disable this requirement.
              If  this  value  is  larger than the value set by --maxdays, the
              user cannot change the pasword.

       -M, --maxdays=days
              Require changing the password after  days  since  last  password
              change.  Set days to -1 to disable password expiration.

       -W, --warndays=days
              Start  warning the user days before password expires (before the
              user is required to change the password).  Set days to 0  or  -1
              to disable the warning.

EXIT STATUS
       The exit status is 0 on success, nonzero on error.

NOTES
       Note  that  "account  expiration"  (set  by  --expire) is distinct from
       "password expiration" (set by --maxdays).  Account  expiration  happens
       on a fixed date regardless of password changes.  Password expiration is
       relative to the date of last password change.
