In the ever-evolving landscape of web development, security is paramount. As we move beyond traditional username and password authentication, technologies like WebAuthn (Web Authentication) are gaining prominence for their ability to provide robust security while offering a seamless user experience.

In this article, we’ll explore Web Authentication and delve into practical examples of how to implement it using JavaScript. No complex jargon — just simple, effective insights to bolster your web security game.

Understanding Web Authentication

WebAuthn is a web standard that enables passwordless authentication using public-key cryptography. Unlike traditional methods that rely on passwords, WebAuthn leverages a user’s device as a secure key, making it significantly more resistant to phishing attacks and other security threats.

Setting the Stage

Let’s start by understanding the basic components of WebAuthn:

1. Client: The user’s device or browser.
2. Server: The backend server that validates authentication requests.
