Passwordless authentication using FIDO2, WebAuthn, and passkeys eliminates the largest single attack vector — password compromise. Security testing evaluates: are fallback authentication flows secure (if passwordless fails, does the system fall back to weaker methods)? Is the registration/enrollment process protected against account takeover? Are authenticator attestation and origin validation correctly implemented? Can relying party identifiers be manipulated? And does the implementation handle device loss and recovery securely?
