In an era where online security breaches and cyber threats are becoming increasingly prevalent, the need for a secure and user-friendly authentication method is imperative. Learn about WebAuthn, a revolutionary web standard that aims to enhance online security by eliminating the need for password usage.
WebAuthn (Web Authentication) is a web standard developed by the World Wide Web Consortium (W3C) and supported by major companies such as Google, Apple, IBM, Microsoft, Mozilla, and Intel. It provides a secure and easy-to-use way for website authentication without the use of passwords.
WebAuthn is primarily designed to prevent phishing attacks and enhance security for online accounts.It allows users to authenticate using biometric sensors like fingerprints or face scans, or via hardware tokens like USB security keys.
This is part of a series of articles about authentication.

WebAuthn uses public-key cryptography to provide a secure and easy-to-use authentication mechanism for web applications. It consists of three key components:
To register for WebAuthn, users must first navigate to a web application that supports WebAuthn authentication. The web application then prompts the users to register their authenticator device.
To do this, users must follow the instructions provided by the web application, which typically involve inserting the authenticator device into a USB port or scanning a QR code on the device. Once the device has been registered, the user public key is sent to the web server and stored in a secure manner.
The WebAuthn API authenticator provides a set of JavaScript functions that can be used by web applications to interact with the authenticator device. These functions include creating a new credential, getting a list of stored credentials, and initiating an authentication request.
The WebAuthn login process starts when users navigate to a web application that supports WebAuthn authentication. The users enter their usernames, and the web application sends a challenge to the client devices. The client devices then communicate with the authenticator device to perform the authentication process.
The authenticator device generates a new public-private key pair and creates a new credential. The credential is signed with the private key stored on the authenticator device and is sent back to the client device. The client device then sends the signed credential to the web server for verification.
The web server verifies the signed credential by checking it against the stored public key for the user. If the verification is successful, the user is authenticated, and they are granted access to the web application.
WebAuthn is a powerful authentication standard that can be used in a wide range of web applications and services. Here are a few examples of how WebAuthn can be used:
Notable benefits of implementing WebAuthn include:
However, using WebAuthn to implement robust authentication also introduces some challenges:
Whether you are opting for traditional password authentication or implementing multi-factor authentication (MFA) flows with single-sign on (SSO) or passwordless functionality, Frontegg has you covered. This robust and enterprise-ready user management platform is completely non-intrusive and integration takes just a few minutes, thanks to its plug-and-play nature. It’s also multi-tenant by design to boost scalability.
All of this means that there’s no need for expensive (and frustrating) in-house development and the focus can be maintained on the core tech and innovating new features. Customer satisfaction levels are also improved thanks to the self-served nature of the platform.
