If the three-factor authentication is enabled (the Enable Biometric ID verification checkbox checked in the Change Biometric ID window), the biometric authentication will be required after the user activates the Key, and the PIN for the Key is successfully verified (if the user has set the PIN protection for the Key). The software will automatically read the biometric templates stored on the Key and will offer the user to provide his biometric data (scan the fingerprints, speak the authentication phrase etc.). In case the BIO ID provided by the user is not identical with the templates stored on the Key, the user will be required to repeat the biometric authentication. Authentication routine will be finished only when the data provided by the user will be identical to the biometric templates stored on the Key. The biometric approach ensures that only authorized user can get access to his/her secret data. Thus, even if the Key is lost or stolen, no unauthorized user will get access to secret disk.
