FIDO2 Authentication Standard

A FIDO2 Authentication Standard is an open passwordless authentication standard by FIDO Alliance that enables public key authentication through WebAuthn protocol and CTAP2 protocol integration.

• AKA: Fast Identity Online 2, FIDO2 Standard, WebAuthn/CTAP2 Standard.
• Context:
  • It can typically implement FIDO2 Authentication Challenge-Response through FIDO2 authentication server verification.
  • It can typically store FIDO2 Authentication Credentials using FIDO2 authentication public key cryptography.
  • It can typically prevent FIDO2 Authentication Phishing Attacks via FIDO2 authentication origin binding.
  • It can typically support FIDO2 Authentication Factors including FIDO2 authentication biometrics and FIDO2 authentication PINs.
  • It can typically enable FIDO2 Authentication Attestation through FIDO2 authentication certificate validation.
  • ...
  • It can often integrate FIDO2 Authentication Passkeys with FIDO2 authentication platform synchronization.
  • It can often provide FIDO2 Authentication Roaming Authenticators via hardware security keys.
  • It can often support FIDO2 Authentication Resident Credentials for FIDO2 authentication usernameless flows.
  • It can often enable FIDO2 Authentication Cross-Platform compatibility across FIDO2 authentication devices.
  • ...
  • It can range from being a Basic FIDO2 Authentication Standard to being an Extended FIDO2 Authentication Standard, depending on its FIDO2 authentication feature scope.
  • It can range from being a Platform-Only FIDO2 Authentication Standard to being a Cross-Platform FIDO2 Authentication Standard, depending on its FIDO2 authentication device support.
  • ...
  • It can integrate with Authentication Service Providers for FIDO2 authentication deployment.
  • It can connect to Identity Management Systems for FIDO2 authentication user management.
  • It can interface with Hardware Security Keys for FIDO2 authentication physical verification.
  • It can communicate with Browser Authentication APIs for FIDO2 authentication web implementation.
  • ...
• Example(s):
  • FIDO2 Authentication Standard Implementations, such as:
    • Platform FIDO2 Authentication Implementations, such as:
      • Windows Hello FIDO2 Authentication for FIDO2 authentication biometric login.
      • Apple Passkey FIDO2 Authentication for FIDO2 authentication iCloud synchronization.
      • Android FIDO2 Authentication for FIDO2 authentication mobile access.
    • Service FIDO2 Authentication Implementations, such as:
      • Google FIDO2 Authentication Service enabling FIDO2 authentication account protection.
      • Microsoft FIDO2 Authentication Platform supporting FIDO2 authentication enterprise deployment.
      • GitHub FIDO2 Authentication providing FIDO2 authentication developer security.
  • FIDO2 Authentication Standard Applications, such as:
    • Enterprise FIDO2 Authentication Deployments, such as:
      • Banking FIDO2 Authentication System for FIDO2 authentication financial security.
      • Healthcare FIDO2 Authentication Platform ensuring FIDO2 authentication HIPAA compliance.
    • Consumer FIDO2 Authentication Services, such as:
      • Social Media FIDO2 Authentication protecting FIDO2 authentication user accounts.
      • E-commerce FIDO2 Authentication securing FIDO2 authentication payment processes.
  • ...
• Counter-Example(s):
  • TOTP Authentication Method, which uses time-based shared secrets rather than FIDO2 authentication public key cryptography.
  • SMS Authentication Method, which relies on telecommunication network delivery rather than FIDO2 authentication local verification.
  • OAuth Authentication Protocol, which focuses on authorization delegation rather than FIDO2 authentication identity verification.
