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 significantly 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 52.

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 about how to set a password, see “Setting, changing, or deleting a password” on page 52.

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 configuration settings, you must use your administrator password.
