The PC-BSD User Manager utility allows you to easily add and delete users and groups on your system, as well as change a user's or the administrative password. To access this utility, go to Application Launcher -> System Settings -> Password & User Account. After inputting the administrative password, you should see a screen similar to Figure 7.6a, though the names of your users accounts will vary:

In this example, the system has 2 user accounts. The "dru" account has the ability to become the superuser as the "Can administrate system" checkbox is checked. The password for any user can be changed by first highlighting the user name then clicking the "Change Password" button. Since the superuser is is using this utility, you will not be prompted for the old password in order to reset the password; this can be handy if a user has forgotten their password and can no longer log into the PC-BSD system. If you click the "Change Admin Password" button, you can change the password that is used whenever you are prompted for administrative access.
