# `auth_plug`

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

[![Build Status](](
[![ dependency status](](

## Why? 🤷

You want a way to add authentication
to your Elixir/Phoenix App
in the fewest steps and least code.
We did too. So we built `auth_plug`.

***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.

### Pain 😧

We try to maintain a
["beginner's mind"](
in everything we do.

There are virtually infinite options
for 3rd party Authentication.
Most are complex and unfriendly to beginners.
They require understanding the difference
between an authentication scheme, strategy or implementation.
We have used everything from
[black box](
(closed source)
services that promise the world but are consistently
painful to setup, to open source projects that
are woefully undocumented and lack automated tests
so we cannot _rely_ on them.
We got tired of compromising on the UX of auth,
so we built _exactly_ what we wanted
as the "users" of our own product.


## 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!
