Password considerations
A password can be any combination of up to twelve characters (a-z and 0-9) and
symbols. For security reasons, it is a good idea to use a strong password that
cannot be easily compromised. Strong passwords typically adhere to the following
rules:
v
Have at least eight characters in length
v Contain at least one alphabetic character, one numeric character, and one symbol
v
Contain at least one of the following symbols: , . / ` ; ' []
v You can also use the space bar
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
User Password
When a User Password is set, the user is prompted to type a valid password each
time the computer is turned on. The computer cannot be used until a valid
password is typed from the keyboard.
Administrator Password
Setting an Administrator Password deters unauthorized persons 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:
