Web Authentication
Web Authentication (WebAuthn) is a web standard that enables passwordless authentication using public-key cryptography, allowing users to log in to websites and applications with biometrics (like fingerprints or facial recognition), security keys, or mobile devices. It is part of the FIDO2 project and provides a secure alternative to traditional passwords by eliminating phishing risks and credential theft. The standard is supported by modern web browsers and operating systems, facilitating seamless and strong authentication across platforms.
Developers should learn and implement Web Authentication to enhance security and user experience in web applications, particularly for high-stakes scenarios like banking, healthcare, or enterprise systems where password breaches are a concern. It is essential for building modern, secure applications that comply with regulations like GDPR or PSD2, and it reduces reliance on passwords, which are vulnerable to attacks such as phishing and brute force. Use cases include single sign-on (SSO), multi-factor authentication (MFA), and access control for sensitive data.
