FIDO Authentication

A passwordless authentication standard that uses biometrics or hardware keys for secure access.

Understanding FIDO Authentication


FIDO Authentication relies on public-key cryptography rather than shared secrets (like passwords). When a user registers, the system generates a key pair, with the private key stored securely on the user’s device and the public key stored on the authentication server.

How FIDO Authentication Works


  1. User Registration – A unique cryptographic key pair is generated and associated with the user’s identity.

  2. Challenge-Response Authentication – Instead of sending a password, the user’s device cryptographically signs an authentication challenge to verify identity.

  3. Passwordless Authentication – Users authenticate using biometric data (fingerprint, facial recognition), security tokens, or USB/NFC devices.

Common Applications of FIDO Authentication


1. Passwordless Login for Websites & Apps

  • Reduces phishing risks by eliminating password-based attacks.

2. Multi-Factor Authentication (MFA)

  • Can be combined with other security measures for stronger authentication.

3. Enterprise & Cloud Security

  • Used for securing corporate networks, cloud accounts, and financial transactions.
