Passwordless Authentication Compliance Requirements

There is no password field. This is passwordless authentication, and its compliance requirements are not optional.

Passwordless systems replace static credentials with methods like WebAuthn, FIDO2 security keys, magic links, or biometric verification. They reduce phishing risk and credential stuffing, but every implementation must follow strict regulatory and industry rules.

To meet passwordless authentication compliance requirements, start with identity verification. Regulations like NIST SP 800-63B define assurance levels that your factor strength must meet. Hardware-based keys can reach AAL3; device-bound biometrics may map to lower levels unless paired with secure attestation.

Next is data protection. Even if no password is stored, you must secure public keys, usage logs, and user identifiers under GDPR or CCPA. Encrypt data in transit and at rest. Follow retention limits — regulators can consider logs containing identifiers as personal data.

Authentication flows must also address accessibility and inclusivity. The Americans with Disabilities Act and WCAG guidelines apply to login experiences. If you rely on biometric sensors, ensure an alternative route exists that meets the same assurance level.

Vendor selection matters. Compliance extends to service providers under SOC 2, ISO 27001, or PCI DSS if payment systems are involved. Verify that any external identity platform has documented audit trails, security controls, and jurisdictional coverage matching your user base.

Testing and audit readiness are non-negotiable. Store documentation showing your passwordless method’s compliance mapping to applicable frameworks. Prepare for penetration testing and security review. Ensure your implementation is resilient against replay attacks, man-in-the-middle exploits, and hardware cloning.

The shift to passwordless can improve security, speed, and user trust — but only if compliance is built into the architecture from the start. Skipping requirements risks regulatory penalties and breaches that damage your brand.
