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 set‐
              tings).

              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 expira‐
              tion.


       -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 pass‐
              word).  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  pass‐
              word expiration.


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