Biometric authentication is one factor in the authentication equation, specifically something you are. Defeating a well-implemented identity system requires compromising multiple independent mechanisms simultaneously, and biometrics alone do not provide that depth. xAuth supports the complete factor library across knowledge, possession, and biometric categories, including xFace server-side verification, voice biometrics via xVoice, passkeys, TOTP, push notifications, and registered device signals. Layering factors also improves resilience when one factor encounters environmental limitations. Daon customers who offer multiple biometric options rather than a single factor report near-elimination of biometric login failure, because when one factor cannot be used due to conditions, another succeeds. Stronger layering means a higher cost for any attacker to overcome.
