Chapter 5. Using the Setup Utility keyboard. The keys used to perform various tasks are displayed on the right side of each screen. Using passwords By using the Setup Utility program, you can set passwords to prevent unauthorized persons from gaining access to your computer and data. See "Starting the Setup Utility program." The following types of passwords are available: • Supervisor Password • User Password You do not have to set any passwords to use your computer. However, if you decide to set any passwords, read the following sections. Password considerations A password can be any combination of up to ten characters (a-z and 0-9) and symbols. For security reasons, it is a good idea to use a strong password that cannot be easily compromised. We suggest the passwords should adhere to the following rules: • Must have at least seven characters in length • Contain at least one alphabetic character, one numeric character. • Setup Utility program and hard disk drive passwords are not case sensitive • Not be your name or your user name • Not be a common word or a common name • Be significantly different from your previous password Supervisor password When a Supervisor Password is set, it deters unauthorized persons from changing configuration settings. If you are responsible for maintaining the settings of several computers, you might want to set a Supervisor Password. After you set a Supervisor Password, a password prompt is displayed each time you try to access the Setup Utility program. If both the supervisor and user passwords are set, you can type either password. However, to change any configuration settings, you must use your supervisor password. 17
