What can I do with this system value?

You can specify whether user passwords expire. You can control the number of days allowed before a password must be changed. If a user attempts to sign on after the password has expired, the system gives the user an opportunity to change the password, and then the user is allowed to sign on.

The suggested setting is from 30 to 90 days.

This system value has the following options:

Never expire (*NOMAX)
Users are not required to change their passwords.
Days after last change (1-366)
Specify the number of days before users are required to change their passwords. Select a value from 1 through 366.
