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.”
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.”
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.
