Securing Your Computer
Passwords
About Passwords
NOTE:
Passwords are disabled when you receive your computer.
A primary password, an administrator password, and a hard drive password all
prevent unauthorized access to your computer in different ways. The
following table identifies types and features of passwords available on your
computer.
NOTE:
Some hard drives do not support hard drive passwords.
NOTICE:
Passwords provide a high level of security for data in your computer or
hard drive. However, they are not foolproof. If you require more security, obtain and
use additional forms of protection, such as smart cards, data encryption programs,
or PC Cards with encryption features.
When using passwords, observe the following guidelines:
• Choose passwords that you can remember, but not ones that are easy to
guess. For example, do not use the names of family members or pets for
passwords.
• It is recommended that you do not write down passwords. If you do write it
down, however, ensure that the password is stored in a secure place.
• Do not share passwords with other people.
• Ensure that people are not watching you when you type your password(s).
