Password policies define each user’s password length, format, and frequency of change. These policies are assigned to a security domain and determine password requirements for all users managed by the security domain.
When you edit a password policy, you can change information such as the name of the password policy, minimum and maximum lifetime information, and character requirements.
In the Security Console, click Authentication > Policies > Password Policies > Manage Existing.
Click the policy that you want to edit, and select Edit.
Make the necessary changes to the password policy.
If you have not saved your changes, you can click Reset to restore the password policy to its original state.
