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–maxdaysand 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
libuserconfiguration. -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.
