Failed Biometric Authentication

There are several scenarios in which biometric authentication may not work:

• True Non-Match: The person attempting to log in is not the individual who initially registered.
• The spoofing assault was halted by True Rejection from Face Liveness Detection.
• False Non-Match: The individual attempting to authenticate is the same person who registered, but the biometric score generated by the matching algorithm falls below the acceptance threshold.
• Inaccurate Rejection from Face Liveness Identification

It is important to note that such messages are rarely shown to regular users and are primarily presented to individuals attempting to compromise the system. This understanding is key to crafting appropriate messaging.

The notifications accessible within the UI SDK and sites accessible to end users do not reveal the reason for denial, that is, the specific AI component (matching/liveness) that denied the authentication.

authID permits three authentication attempts per transaction. During the first two attempts, the user or SDK is directed to the VerifyMatchFail page, indicating that retries are allowed. On the final attempt, the process concludes on the VerifyFinalFail page.
