An introduction to WebAuthn

WebAuthn is a passwordless authentication technology that leverages device biometrics, such as FaceID or TouchID, or hardware keys like YubiKey to offer secure and user-friendly authentication for web applications. It enhances security by utilizing public-key cryptography and is less vulnerable to phishing attacks compared to traditional methods like passwords or SMS-based two-factor authentication. Despite its advantages, widespread adoption of WebAuthn has been slow due to historical challenges in integration and limited device support, though these barriers are now diminishing. Stytch addresses these challenges by simplifying the integration process for developers, making it easier to implement WebAuthn and combine it with other authentication methods for seamless cross-device access and account recovery. As device compatibility improves and integration becomes more straightforward, WebAuthn is expected to gain more traction among applications seeking a secure, low-friction user authentication experience.
