lchage − Display or change user password policy
lchage [OPTION]... user
Displays or allows changing password policy of user.
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.)
Set the account expiration date to days after Jan 1 1970. Set days to -1 to disable account expiration.
Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration.
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.
Only list current user’s policy and make no changes.
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.
Require changing the password after days since last password change. Set days to -1 to disable password expiration.
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.
The exit status is 0 on success, nonzero on error.
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.
