# Authex

[![Build Status](](
[![Authex Version](](

Authex is a simple JWT authentication and authorization library for Elixir.

## Installation

The package can be installed by adding `authex` to your list of dependencies in `mix.exs`:

def deps do
    {:authex, "~> 0.3.3"}

## Documentation

See [HexDocs]( for additional documentation.

## Example

To get started, we must define our auth module:

defmodule MyApp.Auth do
  use Authex, otp_app: :my_app

  # Use the runtime init callback to dynamically set our secret.
  def init(config) do
    secret = System.get_env("AUTH_SECRET") || "secret"
    config = Keyword.put(config, :secret, secret)

    {:ok, config}

And add it to your supervision tree:

children = [

We can then create, sign, and verify tokens:

token = MyApp.Auth.token(sub: 1, scopes: ["admin/read"])
compact_token = MyApp.Auth.sign(token)
{:ok, token} = MyApp.Auth.verify(compact_token)

Please check out the documentation for more advanced features like serializers,
repositories and integration with plugs.

## Features

- Easy to integrate with almost any app.
- Handles both authentication + authorization.
- Compatible with umbrella apps.
- Convert data to and from tokens via serializers.
- Handle persistence for things like blacklists.
- Batteries included for plug integration.
