Understanding Passkeys
How passkeys and WebAuthn work for secure authentication
What are Passkeys?
Passkeys are a passwordless authentication method based on FIDO2/WebAuthn standards. They use public-key cryptography to provide strong, phishing-resistant authentication.
Device Authentication
Passkeys leverage built-in authenticators like Touch ID, Face ID, Windows Hello, or security keys to verify user identity using biometrics or device PINs.
Security Benefits
Unlike passwords, passkeys cannot be phished, stolen in breaches, or reused across sites. Each credential is unique to the specific website and user.
