Passkey

A Passkey is an authentication credential that enables passwordless authentication through public-key cryptography.

• AKA: FIDO Passkey, WebAuthn Passkey, Passwordless Key.
• Context:
  • It can typically enable Passkey Authentication across passkey-compatible devices through passkey authentication protocols.
  • It can typically provide Phishing-Resistant Authentication through passkey cryptographic verification.
  • It can typically support Cross-Platform Authentication through passkey synchronization mechanisms.
  • It can typically implement FIDO2 Standard Compliance through passkey FIDO2 protocols.
  • It can typically eliminate Password-Related Vulnerability through passkey cryptographic methods.
  • ...
  • It can often integrate with Password Manager Systems through passkey storage interfaces.
  • It can often synchronize across Multiple User Devices through passkey cloud synchronization.
  • It can often provide Biometric Authentication Support through passkey biometric integration.
  • It can often enable Account Recovery Process through passkey recovery mechanisms.
  • ...
  • It can range from being a Device-Bound Passkey to being a Syncable Passkey, depending on its passkey portability characteristic.
  • It can range from being a Platform Passkey to being a Cross-Platform Passkey, depending on its passkey platform scope.
  • It can range from being a Single-Factor Passkey to being a Multi-Factor Passkey, depending on its passkey authentication factor count.
  • It can range from being a Consumer Passkey to being an Enterprise Passkey, depending on its passkey deployment context.
  • ...
  • It can integrate with Web Browser for passkey web authentication.
  • It can connect to Mobile Operating System for passkey mobile authentication.
  • It can interface with Identity Provider System for passkey identity federation.
  • It can communicate with Authentication Server for passkey verification process.
  • It can synchronize with Cloud Storage Service for passkey backup operation.
  • ...
• Example(s):
  • Platform-Specific Passkeys, such as:
    • Apple Passkey stored in iCloud Keychain for Apple ecosystem authentication.
    • Google Passkey managed through Google Password Manager for Google account authentication.
    • Microsoft Passkey integrated with Windows Hello for Microsoft service authentication.
  • Password Manager Passkeys, such as:
    • 1Password Passkey stored in 1Password vault for cross-platform passkey authentication.
    • LastPass Passkey managed by LastPass Password Manager for unified passkey management.
    • Dashlane Passkey synchronized through Dashlane service for secure passkey storage.
  • Enterprise Passkey Implementations, such as:
    • Corporate Single Sign-On Passkey for enterprise authentication systems.
    • Banking Passkey for financial service authentication.
    • Healthcare System Passkey for medical record access control.
  • ...
• Counter-Example(s):
  • Traditional Password, which uses memorized strings rather than cryptographic key pairs.
  • SMS OTP Authentication, which relies on phone number verification rather than cryptographic proof.
  • Security Question, which uses knowledge-based authentication rather than cryptographic credentials.
  • Physical Security Key, which requires hardware token presence rather than synchronized passkey credentials.
