Password considerations

A password can be any combination of up to 12 (1 to 12) alphabetic and numeric characters (a-z and 0-9). For security reasons, it is recommended to use a strong password that cannot be easily compromised. A strong password should adhere to the following rules:

vHave at least eight characters in length and contain at least one alphabetic character and one numeric character

vSetup Utility program and hard disk drive passwords are not case sensitive

vNot be your name or your user name

vNot be a common word or a common name

vBe significantly different from your previous password

User Password

When a User Password is set, the computer cannot be used until a valid password is typed in.

Administrator Password

When an Administrator Password is set, it deters unauthorized people from changing configuration 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 configuration settings, you must use your administrator password.

Setting, changing, and deleting a password

To set, change, or delete a password, do the following:

Note: A password can be any combination of up to 12 (1 to 12) alphabetic and numeric characters. For more information, see “Password considerations.”
