Chapter 27. Defining Password Policies

This chapter describes what password policies in Identity Management (IdM) are and how to manage them.

27.1. What Are Password Policies and Why Are They Useful

A password policy is a set of rules that passwords must meet.
For example, a password policy can define minimum password length and maximum password lifetime. All users affected by such a policy are required to set a sufficiently long password and change it frequently enough.
Password policies help reduce the risk of someone discovering and misusing a user's password.
