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.
