WebAuthn is a web standard developed by the W3C and FIDO Alliance that enables robust, phishing-resistant authentication using public key cryptography instead of traditional passwords.

Passwordless authentication replaces phishable, shared secrets like passwords with public-key cryptography.

Secure QR login authentication is an out-of-band authentication mechanism that uses a visual matrix to transmit a short-lived cryptographic rendezvous challenge between an untrusted browser.

Organizations adopting phishing-resistant MFA move beyond OTP challenges to hardware-backed WebAuthn authenticators that verify the origin of each attempt.
