Securing Your Computer: Dell Latitude D620 User's Guide Using Smart Cards NOTE: For information on how to secure your computer while traveling, see Traveling With Your Computer. NOTE: The smart card feature may not be available on your computer.About Smart CardsSmart cards are portable credit-card shaped devices with internal integrated circuits. The top surface of the smart card usually contains an embedded processor under the gold contact pad. The combination of the small size and integrated circuits make smart cards valuable tools for security, data storage, and special programs. Using smart cards can improve system security by combining something a user has (the smart card) with something only the user should know (a PIN) to provide more secure user-authentication than passwords alone.Installing a Smart CardYou can install a smart card in the computer while the computer is running. The computer automatically detects the card.To install a smart card:1.

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). file:///H|/My%20Documents/Cellular/User%20Guides/Notebooks/D620/UG_en/security.htm (4 of 9)4/12/2007 9:36:12 AM
Securing Your Computer: Dell Latitude D620 User's Guide 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. If you forget any of your passwords, contact Dell (see Contacting Dell). For your protection, Dell technical support staff will ask you for proof of your identity to ensure that only an authorized person can use the computer.Using a Primary (or System) PasswordThe primary password allows you to protect the computer from unauthorized access.When you first start your computer, you must assign a primary password at the prompt.If you do not enter a password within 2 minutes, the computer returns to its previous operating state. NOTICE: If you disable the administrator password, the primary password is also disabled.To add or change passwords, access User Accounts from the Control Panel. If you have assigned an administrator password, you can use it instead of the primary password. The computer does not specifically prompt you for the administrator password.Using an Administrator PasswordThe administrator password is designed to give system administrators or service technicians access to computers for repair or reconfiguration. The administrators or technicians can assign identical administrator passwords to groups of computers, allowing you to assign a unique primary password.To set or change administrator passwords, access User Accounts from the Control Panel.When you set an administrator password, the Configure Setup option becomes available in system setup. The Configure Setup option allows you to restrict access to system setup in the same way that a primary password restricts access to the computer.The administrator password can be used instead of the primary password.
