Set User Password
After you have set a User Password using the Set User Password option, the user is prompted to type
a valid User Password each time the computer is turned on. The computer cannot be used until a valid
User Password is typed in. For more information on how to set a password, see “Setting, changing, and
deleting a password” on page 38.
Set 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, and 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 Administrator
Password is typed in.
If you have set both the User Password and the Administrator Password, you can type either password.
However, to change any configuration settings, you must use your Administrator Password.
