Password considerations
A password can be any combination of up to 64 (1 to 64) 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.
v
Have at least eight characters in length
v Contain at least one alphabetic character and one numeric character
v
Not be your name or your user name
v
Not be a common word or a common name
v
Be significantly different from your previous passwords
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, or 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 password is typed in.
If you have set both a user 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.
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
on how to set a password, see “Setting, changing, or deleting a password.”
Hard disk drive password
The Hard Disk Password option enables you to set a hard disk drive password,
which prevents unauthorized access to the data on the hard disk drive. When a
hard disk drive password is set, you are prompted to type a valid password each
time you try to access the hard disk drive. For more information on how to set a
hard disk drive password, see “Setting, changing, or deleting a password.”
