WebAuthn

Overview

WebAuthn (Web Authentication) is a global web standard for secure, passwordless authentication using public-key cryptography. It allows users to log in with biometrics, hardware tokens, or device-based credentials instead of passwords.

Private keys remain on the device, while public keys are registered with the service, preventing credential reuse and phishing. Regulators and cybersecurity frameworks encourage WebAuthn as part of strong customer authentication (SCA) and zero-trust strategies. Banks, fintechs, and digital platforms adopt WebAuthn to protect logins, payments, and compliance-sensitive services. By eliminating weak passwords and OTP reliance, WebAuthn strengthens security and improves user experience.
