+# Face Liveness
+
+Amplify UI Face Liveness provides a UI component (FaceLivenessDetector) that helps developers deter fraud and scams during face-based identity checks by validating that users are physically present in front of the camera at that moment, and not an imposter spoofing the user's face.
+
+More information on setting up and using the FaceLivenessDetector is in the [Amplify UI Face Liveness documentation](https://ui.docs.amplify.aws/android/connected-components/liveness).
