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:
v
Have at least eight characters in length
v Contain at least one alphabetic character and one numeric character
v
Setup Utility program and hard disk drive passwords are not case sensitive
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 password
Power-On Password
When a Power-On Password is set, the computer cannot be used until a valid
password is typed in.
Privileged Access Password
When a Privileged Access 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 a Privileged Access Password.
After you set a Privileged Access Password, a password prompt is displayed each
time you try to access the Setup Utility program.
If both the Power-On Password and Privileged Access Password are set, you can
type either password. However, to change any configuration settings, you must use
your Privileged Access Password.
Setting, changing, and deleting a password
