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.
