 # 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.
+Amplify FaceLivenessDetector provides a UI component for [Amazon Rekognition Face Liveness](https://aws.amazon.com/rekognition/face-liveness/) feature that helps developers verify that only real users, not bad actors using spoofs, can access your services.
 
 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).
