Password considerations
A password can be any combination of up to 12 (1 to 12) alphabetic and numeric characters. For security
reasons, it is recommended to use a strong password that cannot be easily compromised. To set a strong
password, use the following guidelines:
Note: The Setup Utility program passwords are not case sensitive.
• Have at least eight characters in length
• Contain at least one alphabetic character and one numeric character
• Not be your name or your user name
• Not be a common word or a common name
• Be significantly different from your previous passwords
Administrator password
The Set Administrator Password option enables you to set an administrator password, which deters
unauthorized users from changing configuration settings. If you are responsible for maintaining the settings
of several computers, you might want to set an administrator password. For more information on how to set
a password, see “Setting, changing, or deleting a password” on page 38.
After you have set an administrator password, a password prompt is displayed each time you try to access
the Setup Utility program. You cannot access the Setup Utility program until a valid password is typed in.
If you have set both a user password and an administrator password, you can type either password to use
your computer. However, to change any configuration settings, you must use your administrator password.
User Password
After you have set a user password using the Set User Password option, the computer cannot be used until
a valid password is typed in.
