# `auth_plug` The Elixir Plug that _seamlessly_ handles all your authentication/authorization needs.

Why? 🤷

Frustrated by the complexity and incomplete docs/tests in existing auth solutions, we built auth_plug to simplify our lives. We needed a way to minimise the number of steps and amount of boilerplate code required to add auth in our app(s). auth_plug allows us to setup auth in any Elixir/Phoenix App in less than 2 minutes and only 7 lines of code.

What?

A plug a complete beginner can use to add auth to a Phoenix App and understand how it works. No macros/behaviours to use (confuse). No complex configuration. No genservers or extra OTP apps. Just a basic plug that uses Phoenix Sessions and standards-based JSON Web Tokens (JWT). Refreshingly simple. The way auth should be done.

Who? 👥

We built this plug for use in our products/services. It does exactly what we want it to and nothing more. It's tested, documented and open source the way all our code is. It's not yet a general purpose auth solution that anyone can use. If after reading through this you feel that this is something you would like to have in your own Elixir/Phoenix project, let us know!
