What is WebAuthn?

WebAuthn, a specification of the Web Authentication API developed by the World Wide Web Consortium (W3C), enables passwordless authentication through public-key cryptography and supports various authenticator types, such as device biometrics and secure hardware keys. It integrates seamlessly with multi-factor authentication (MFA) and universal second-factor authentication (U2F) protocols, providing enhanced security against phishing and cyber attacks by using unique keys for encryption and decryption. Despite challenges like inconsistent browser support, WebAuthn is gaining traction for its reduced user friction and high security, with tools like Stytch's WebAuthn product simplifying its implementation. As it continues to evolve, the standard is expected to become more universally supported, offering a versatile solution for secure identity verification.
