Correct Answer
A web authentication standard using public-key cryptography and hardware authenticators (passkeys, security keys) to eliminate password-based authentication
Explanation
WebAuthn (W3C) + CTAP2 = FIDO2. Uses device-bound private keys (no password server-side). Phishing-resistant: signatures are bound to the origin. Passkeys (synced credentials) extend this to multi-device use.
