Web Authentication and Credential Management APIs for Developers

Modern web users expect seamless and secure login experiences without repetitive form filling. Implementing standard browser authentication APIs allows your web applications to securely interact with the browser's credential manager, improving both security and user experience. This course teaches you how to programmatically manage user credentials and prepare your applications for passwordless authentication. You will begin by understanding the core security concepts of web-based credential storage and browser-based managers. Next, you will learn how to implement the Credential Management API to retrieve, store, and prevent automatic sign-ins when necessary. Finally, you will explore modern authentication trends, including an introduction to the Web Authentication (WebAuthn) API for secure, passwordless public-key cryptography. What you will learn: - Understand the fundamentals of browser-based credential storage and security boundaries. - Implement the Credential Management API to retrieve and store user credentials. - Handle exceptions gracefully when password managers are disabled or unavailable. - Configure federated identity credentials to support third-party login providers. - Understand the basics of WebAuthn and passwordless authentication flows. - Practice writing clean JavaScript to manage user sessions securely. This text-based course guides you step-by-step through foundational concepts, API syntax, and practical implementation patterns. You will read clear explanations and review practical code snippets designed to be implemented immediately. This course is designed for web developers who want to modernise their authentication flows. A basic understanding of HTML and JavaScript is recommended, but no prior experience with browser credential APIs is required.
