Phoenix LiveView Authentication: Securing Real-Time Web Apps

Building real-time web applications with Phoenix LiveView is incredibly powerful, but keeping user data secure requires a solid understanding of real-time authentication. Traditional request-response security patterns do not automatically apply to persistent WebSocket connections. In this text-only course, you will learn how to design, implement, and maintain secure authentication and authorization flows inside your Phoenix LiveView applications. You will transition from basic security concepts to protecting routes, managing active sessions, and identifying logged-in users instantly as they interact with your real-time components.\n\nWhat you'll learn:\n- Understand the core differences between HTTP-based authentication and persistent WebSocket security in LiveView.\n- Implement secure user registration and login flows using modern Phoenix authentication generators.\n- Configure route-level protection to ensure only authorized users can access specific LiveView pages.\n- Apply the on_mount lifecycle hook to share and verify session data across multiple live views efficiently.\n- Manage real-time user state and handle session termination or disconnection gracefully.\n- Practice writing clean, maintainable security policies for your Elixir-based web applications.\n\nThe course begins with foundational concepts of web security and session management before moving into hands-on configuration of LiveView-specific lifecycle hooks. You will read through practical, step-by-step code explanations that demonstrate how to lock down your application without sacrificing user experience. This course is designed for web developers and Elixir beginners who want to secure their applications. No prior experience with security engineering is required, though a basic familiarity with Phoenix and LiveView is helpful.
