Passkeys & Passwordless
WebAuthn / FIDO2
Fully supported in Keycloak 26.x — let users authenticate with biometrics, hardware keys, or platform authenticators. Eliminates phishing and credential-stuffing attacks entirely.
How It Works
Technical Highlights
How It Works
Users register a FIDO2 credential on their device — Touch ID, Face ID, Windows Hello, or a hardware security key. On subsequent logins, the browser’s WebAuthn API negotiates a cryptographic challenge with Keycloak’s FIDO2 verifier, issuing a JWT upon successful assertion. No shared secret ever leaves the device.
Security Benefits
Passkeys are phishing-proof by design: the credential is cryptographically bound to the relying party’s origin, making man-in-the-middle and credential replay attacks impossible. Combined with device-level biometric gating, this eliminates the top two enterprise attack vectors — phishing and credential stuffing.
Migration from Passwords
Keycloak supports progressive enrollment where existing password users are prompted to register a passkey on their next login. Fallback authentication flows ensure continuity during migration, and admin policies can enforce passkey-only access per realm, group, or client once adoption targets are met.
Why in 2026
Passwords are dead in 2026. Apple, Google, and Microsoft all default to passkeys. Your IAM must too.
