Route Authentication in Phoenix Using Plugs

Building web applications requires a robust strategy for protecting sensitive routes and managing user identities. Without proper access control, your application remains vulnerable to unauthorized access. This text-based course guides you through the process of securing your Phoenix applications using Plugs. You will transition from understanding basic web requests to implementing custom pipeline middleware that intercepts, validates, and routes users based on their authentication state. During this course, you will: Understand the fundamental role of Plugs in the Phoenix connection lifecycle; Build custom authentication plugs to inspect, assign, and validate user credentials; Manage user sessions securely using modern session storage configurations; Configure router pipelines to restrict access to sensitive application routes; Test your authentication plugs effectively using standard testing tools. You will begin with core concepts of connections and middleware before moving into step-by-step implementation of custom session-based authentication and route filtering. This course is designed for beginner Phoenix developers looking to implement secure access controls, and no prior security or authentication experience is required. Start securing your Phoenix applications today with clean, maintainable plug architectures.
