Securing Your Tablet-PC 112
Smart cards are portable credit-card shaped devices with internal integrated
circuits. 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. See "Smart Cards" on page 91 for more information.
A biometric reader is a strip sensor located on your Tablet-PC’s display. When
you slide your finger over the reader, it uses your unique fingerprint to
authenticate your user identity and help keep your Tablet-PC secure.
NOTE: You must purchase optional software in order to configure and use your
biometric reader. See the documentation that ships with the biometric software for
further information.
Passwords
About Passwords
NOTE: Passwords are disabled when you receive your Tablet-PC.
A primary (or system) password, an administrator password, and a hard drive
password all prevent unauthorized access to your Tablet-PC in different ways.
The following table identifies types and features of passwords available on
your Tablet-PC.
NOTE: Some hard drives do not support hard drive passwords.
Type of Password Features
Primary (or system) • Protects the Tablet-PC from unauthorized
access
Administrator • Gives system administrators or service
technicians access to Tablet-PCs for repair or
reconfiguration
• Allows you to restrict access to system setup in
the same way a primary password restricts access
to the Tablet-PC
• Can be used instead of the primary password
Hard drive • Helps protect the data on your hard drive or
external hard drive (if one is being used) from
unauthorized access
