OPTIONS

18       -d, --date=days
19              Set the date of last password change to days after Jan 1 1970.
20
21              Set  days  to  -1 to disable password expiration (i.e. to ignore
22              --mindays, and --maxdays and related settings).
23
24              Set days to 0 to enforce password change on next  login.   (This
25              also   disables   password  expiration  until  the  password  is
26              changed.)
27
28
29       -E, --expire=days
30              Set the account expiration date to days after Jan 1  1970.   Set
31              days to -1 to disable account expiration.
32
33
34       -i, --interactive
35              Ask  all questions when connecting to the user database, even if
36              default answers are set up in libuser configuration.
37
38
39       -I, --inactive=days
40              Disable the account after days after password expires (after the
41              user  is  required  to  change the password).  Set days to -1 to
42              keep the account enabled indefinitely after password expiration.
43
44
45       -l, --list
46              Only list current user's policy and make no changes.
47
48
49       -m, --mindays=days
50              Require at least days days between password changes.   Set  days
51              to 0 or -1 to disable this requirement.
52
53              If  this  value  is  larger than the value set by --maxdays, the
54              user cannot change the pasword.
55
56
57       -M, --maxdays=days
58              Require changing the password after  days  since  last  password
59              change.  Set days to -1 to disable password expiration.
60
61
62       -W, --warndays=days
63              Start  warning the user days before password expires (before the
64              user is required to change the password).  Set days to 0  or  -1
65              to disable the warning.

NOTES

73       Note  that  “account  expiration”  (set  by  --expire) is distinct from
74       “password expiration” (set by --maxdays).  Account  expiration  happens
75       on a fixed date regardless of password changes.  Password expiration is
76       relative to the date of last password change.
