Authentication Standards encompass protocols and specifications for verifying user identity in digital systems, particularly FIDO2 and WebAuthn standards that enable passwordless, phishing-resistant authentication using public key cryptography and hardware authenticators for secure access to metaverse platforms and blockchain applications.

Technical Details
Key standards include:
-
FIDO2: FIDO Alliance umbrella standard combining WebAuthn + CTAP (Client-to-Authenticator Protocols)
-
WebAuthn: W3C web standard API for browser-based passwordless authentication (Level 3 in development)
-
Passkeys: FIDO credentials using public key cryptography, unique and domain-bound
Security Benefits
FIDO standards provide phishing-resistant authentication where biometric data never leaves user device. Credentials are bound to specific domains, preventing replay attacks.
Regulatory Recognition
CISA recommends phishing-resistant MFA as gold standard. NIST SP 800-63B identifies FIDO2/WebAuthn as meeting AAL3 (highest assurance level) with hardware authenticators.
Market Adoption
85% of devices worldwide support FIDO2/WebAuthn. Passwordless authentication market projected to reach $61.45 billion by 2032.
