How does xAuth address that?](/discussions/we-need-psd2-strong-customer-authentication-compliance-how-does-xauth-address-that) We need PSD2 Strong Customer Authentication compliance. How does xAuth address that? xAuth is designed to meet PSD2 SCA requirements, which mandate combining two factors from different categories: something you know, something you have, or something you are. FIDO2 passkeys deployed through xAuth satisfy this requirement on their own, combining device possession with a biometric or PIN unlock. xAuth additionally supports phishing-resistant cryptographic authentication and is explicitly compliant with PSD2 SCA, FIDO2, and COPPA. xFace carries GDPR, PSD2, and NIST AAL2 compliance with full audit trail logging.

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.

What does xAuth add beyond the standard?](/discussions/we-are-deploying-fido2-passkeys-what-does-xauth-add-beyond-the-standard) We are deploying FIDO2 passkeys. What does xAuth add beyond the standard? xAuth extends standard passkey deployments with four capabilities that regulated industries regularly encounter. Device registration flagging identifies and acts on passkey transactions presented from unregistered devices. MFA step-up adds strong additional factors for enrollment edge cases or devices that lack passkey support. Transaction Data Signing provides full traceability and non-repudiation of customer actions. And xFace server-side biometric step-up handles high-risk transactions and self-service account recovery where device-level assurance is not sufficient. On TrustX, a passkey can also be automatically generated from an xProof IDV workflow, cryptographically linking the authentication factor to the verified customer identity from day one.
