User Password
When a User Password is set, the computer cannot be used until a valid password is typed from the
keyboard.
Administrator Password
Setting an Administrator Password deters unauthorized users from changing conguration settings. If you
are responsible for maintaining the settings of several computers, you might want to set an Administrator
Password.
After you set an Administrator Password, a password prompt is displayed each time you try to access the
Setup Utility program.
If both the user and administrator passwords are set, you can type either password. However, to change
any conguration settings, you must use your administrator password.
Setting, changing, and deleting a password

1. Start the Setup Utility program. See “Starting the Setup Utility program” on page 17.
2. From the Setup Utility program main menu, select Security Set Passwords.

you want.
