Face SDK Release Notes 8.4 — October 8, 2026

Important Changes

Introduced Enroll and Verify, a new Face SDK capability that simplifies adding biometric authentication to your solution. It combines liveness, face comparison, and person database operations into an integrated enrollment and verification flow. For details, see the Enroll and Verify documentation.
The minimum supported iOS version is now iOS 15. Devices running iOS 14 or earlier are no longer supported.

Updated the neural networks used for liveness presentation attack detection to improve success rates for real users and enhance protection against fraudulent attempts.
Improved the stability of the technology responsible for detecting correct movement during active liveness checks. This helps reduce the false rejection rate.

Fixed an issue where the Close button appeared on the progress screen even when it was disabled.

Fixed an issue where an authentication challenge failed with the CancelAuthenticationChallenge response when optional client-certificate authentication was enabled on the server.

Updated dependencies to the latest available versions to address security vulnerabilities.
