173 Toshiba Utilities Fingerprint Authentication Utility Fingerprint Logon The fingerprint utility enables logon to your computer using fingerprints. During user enrollment, fingerprint samples are saved and associated with your Windows® user account. When you attempt to log on again, your fingerprint is read and compared with your enrolled fingerprints; if the fingerprint is recognized, your logon is completed. The Fast User Switching feature of Windows® XP is also supported. If user A is logged on and the fingerprint utility verifies the fingerprint of user B (who is already enrolled), the utility recognizes the fingerprint and switches users. If your system supports power-on security, existing fingerprint samples can also be used for power-on authentication. The Power-on Security The Power-on security feature prevents unauthorized access to your computer when it is turned off by requiring the user to pass fingerprint authentication. If fingerprint authentication fails, the user will not be able to start the computer. When power-on security is enabled, the system asks you to authenticate your fingerprint. You have 40 seconds to swipe your fingerprint. If the authentication fails, the system tries again up to two more times. If authentication fails after the third attempt, the system shuts down. Enabling Power-on Security Power-on security is enabled automatically after the first user fingerprints are enrolled. To disable/enable power-on security: 1 Open the Control Center and go to Settings - Power-on Security. (This wizard is displayed only if your system supports power-on security.)
