Hardware User Authentication
Users log on to many systems each day, in many cases using unique passwords. Users may be tempted to manage
their passwords by writing them down, while convenient for the user this is one of the leading causes of security
compromise. The AT88SA102S offers an additional level of security for hardware “two factor logon” at a low per user
cost. Configuring the system to communicate with the AT88SA102S prior to allowing user access provides increased
security over password authentication alone. The implementation of a hardware user authentication is displayed in
Figure 11.
