Password considerations
A password can be any combination of up to 16 (1 to 16) 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 signicantly different from your previous passwords
Power-on password
After you have set a power-on password using the Set Power-On Password option, a password prompt is
displayed each time you turn on the computer. You cannot use the computer until a valid password is typed
in. For more information about how to set a password, see “Setting, changing, or deleting a password”
on page 48
.
Administrator password
The Set Administrator Password option enables you to set an administrator password, which deters
unauthorized users from changing conguration settings. If you are responsible for maintaining the settings
of several computers, you might want to set an administrator password. For more information about how to
set a password, see “Setting, changing, or deleting a password” on page 48
.
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 power-on password and an administrator password, you can type either password
to use your computer. However, to change any conguration settings, you must use your administrator
password.
