Auth0 OAuth2 strategy for Überauth.

Installation

  1. Set up your Auth0 application at Auth0 dashboard.

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

    def deps do
      [
        {:ueberauth_auth0, "~> 2.0"}
      ]
    end
  3. Ensure ueberauth_auth0 is started before your application:

    def application do
      [
        applications: [:ueberauth_auth0]
      ]
    end
  4. Add Auth0 to your Überauth configuration:

    config :ueberauth, Ueberauth,
      providers: [
        auth0: {Ueberauth.Strategy.Auth0, []}
      ],
      # If you wish to customize the OAuth serializer,
      # add the line below. Defaults to Jason.
      json_library: Poison

    or with per-app config:

    config :my_app, Ueberauth,
      providers: [
        auth0: {Ueberauth.Strategy.Auth0, [otp_app: :my_app]}
      ]
  5. Update your provider configuration:

    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")

    or with per-app config:

    config :my_app, 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")

    See the Ueberauth.Strategy.Auth0 module docs for more configuration options.

  6. Include the Überauth plug in your controller:

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

    or with per-app config:

    defmodule MyApp.AuthController do
      use MyApp.Web, :controller
      plug Ueberauth, otp_app: :my_app
      ...
    end
  7. Create the request and callback routes if you haven't already:

    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 application.
