Auth0 Integration for Java Servlet Authentication

Securing user data and managing login flows can be one of the most complex parts of web development. This written course guides you through integrating Auth0 with Java Servlet applications to build a robust, modern identity management system. You will start with the foundational concepts of authentication, authorization, and token-based security before diving into practical configuration. By completing this course, you will be able to confidently secure your Java-based endpoints, manage user sessions, and implement modern security practices without relying on complex custom security code. What you'll learn: - Understand the core principles of OAuth 2.0, OpenID Connect, and token-based authentication - Configure an Auth0 tenant and register your Java Servlet application - Implement secure login, logout, and callback endpoints using standard Java APIs - Parse, validate, and extract user profile information from JSON Web Tokens (JWTs) - Apply role-based access control (RBAC) to restrict access to specific servlet routes - Integrate modern security practices including environment-based configuration and secure cookie handling This structured course starts with essential identity terminology and security concepts, then guides you step-by-step through setting up your environment, writing the servlet filter logic, and verifying your secure routes. It is designed specifically for Java developers who are new to identity providers and want a clear, conceptual path to securing their web applications. No prior experience with Auth0 or identity protocols is required, though a basic understanding of Java web applications and servlets is recommended.
