Description: WebAuthn is a web standard for secure authentication using public key cryptography. This protocol allows users to authenticate to web applications and services without the need for passwords, instead using authentication devices such as security keys, biometrics, or hardware authenticators. WebAuthn is part of the FIDO (Fast Identity Online) initiative, which aims to improve security in authentication and reduce reliance on passwords, which are vulnerable to attacks such as phishing and credential theft. By employing public key cryptography, WebAuthn ensures that credentials are never transmitted over the network, minimizing the risk of exposure. This approach not only enhances security but also provides a smoother user experience, as users can authenticate with a simple touch or scan, rather than remembering and typing complex passwords. WebAuthn is compatible with multiple platforms and browsers, making it a versatile and accessible solution for modern authentication.
History: WebAuthn was developed by the FIDO Alliance and the World Wide Web Consortium (W3C), officially launched as a standard in March 2019. Its creation was driven by the need to improve online authentication security and reduce reliance on passwords, which are prone to attacks. The evolution of WebAuthn builds on the accumulated experience of previous FIDO standards, such as U2F (Universal 2nd Factor), which introduced two-factor authentication using hardware devices.
Uses: WebAuthn is primarily used for authentication in web applications and online services, allowing users to securely log in without passwords. It is applicable in various environments, including enterprise applications, e-commerce platforms, online banking services, and social networks, where credential security is critical. Additionally, WebAuthn can be integrated into various devices and operating systems to provide biometric authentication, such as facial recognition or fingerprint scanning.
Examples: Examples of WebAuthn usage include authentication in services where users can log in using security keys like YubiKey or through biometric authentication on mobile devices. It is also used in online gaming platforms that require secure authentication to protect user accounts.
