# Überauth Auth0

> Auth0 OAuth2 strategy for Überauth.

## Installation

  1. Set up your Auth0 application at [Auth0 dashboard](https://manage.auth0.com/#/applications)

  2. Add `ueberauth_auth0` to your list of dependencies in `mix.exs`:

    ```elixir
    def deps do
      [{:ueberauth_auth0, "~> 0.2"}]
    end
    ```

  3. Ensure `ueberauth_auth0` is started before your application:

  ```elixir
  def application do
    [applications: [:ueberauth_auth0]]
  end
  ```

  4. Add Auth0 to your Überauth configuration:

  ```elixir
  config :ueberauth, Ueberauth,
    providers: [
      auth0: {Ueberauth.Strategy.Auth0, []}
    ]
  ```

  5. Update your provider configuration:

  ```elixir
  config :ueberauth, Ueberauth.Strategy.Auth0.OAuth,
    domain: System.get_env("AUTH0_DOMAIN"),
    client_id: System.get_env("AUTH0_CLIENT_ID"),
    client_secret: System.get_env("AUTH0_CLIENT_SECRET")
  ```

  6. Include the Überauth plug in your controller:

  ```elixir
  defmodule MyApp.AuthController do
    use MyApp.Web, :controller
    plug Ueberauth
    ...
  end
  ```

  7. Create the request and callback routes if you haven't already:

  ```elixir
  scope "/auth", MyApp do
    pipe_through :browser

    get "/:provider", AuthController, :request
    get "/:provider/callback", AuthController, :callback
  end
  ```

  8. You controller needs to implement callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses.

  For an example implementation see the [Überauth Example](https://github.com/ueberauth/ueberauth_example) application.
