A W3C standard for phishing-resistant authentication using public-key cryptography and hardware-backed credentials.
WebAuthn (and its consumer-friendly cousin, passkeys) replaces passwords and OTP-based MFA. Credentials are bound to the relying party origin, so phishing sites cannot use them. Passkeys can sync via iCloud Keychain or Google Password Manager for cross-device portability.
See our web application penetration testing, API security testing, network penetration testing, and cloud security audit services for how we test for and defend against this class of issue.
