The Fast User Switching feature of the Windows® operating system 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 the users. If your system supports power-on security, existing fingerprint samples can be used also for power-on authentication. 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 Options for power-on security are displayed only if your computer supports this feature. In most configurations, 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.) 2 Check the option Replace the power-on and hard drive passwords with the fingerprint reader. Power-on security can be configured to operate with the fingerprint logon feature. If a fingerprint used for power-on security matches a fingerprint in an existing passport, the corresponding user is logged on automatically without having to enter the Windows® logon password. Toshiba Utilities 157 Fingerprint Authentication Utility NOTE Your hardware must support Power-on security to use the single logon feature. You must have administrative privileges to change settings. To enable power-on security single logon: 1 Open the Control Center and go to Settings - System Settings. 2 Select Logon. 3 Check the Allow power-on security single sign-on check box. (Logon support must be enabled for this option to be accessible.) Fingerprint Management Fingerprints are stored in memory during enrollment. After a fingerprint is enrolled, it is displayed with a power-on button above it. The button appears “pressed in” by default, indicating that the corresponding finger will be used for power-on security. If you do not want to use a fingerprint for power-on security but only for logon, click the Boot button to delete the fingerprint from the fingerprint device memory. The fingerprint device memory can typically hold up to 21 fingerprints. The number of slots remaining is displayed in the enrollment wizard. Control Center The Control Center contains various functions for fingerprint management and for setting up your fingerprint software. Available options depend on the software status, used hardware, and installed applications. (Sample Image) Main Fingerprint Control Center Window Toshiba Utilities 158 Fingerprint Authentication Utility Fingerprints . Enroll or Edit Fingerprints—Runs the fingerprint enrollment wizard. You can enroll/delete fingerprints for the current user and, if power-on security is implemented, control whether they are stored in the fingerprint device memory. After you enroll your fingerprints, they are associated with your user name and password. The next time you log in, you can use your fingerprints instead of your user name and password. . Delete—Deletes all fingerprints for the current user. Settings . System Settings—Opens the Settings dialog containing various options for setting up the product. Most of these settings can be modified only by administrators and affect all users. . User Settings—Opens the User Settings dialog containing user-specific options for setting up the product. . Power-on Security—The memory of the fingerprint device is limited (typical capacity is 21 fingerprints). You can decide which fingerprints are present in the device memory and can be used for verification on computer startup, or create new fingerprints to be used only for power-on authentication. .
