Getting started


Add the following line to your Gemfile:

gem 'omniauth-auth0'

If you're using this strategy with Rails, also add the following for CSRF protection:

gem 'omniauth-rails_csrf_protection'

Then install:

$ bundle install

See our contributing guide for information on local installation for development.

Configure the SDK

Adding the SDK to your Rails app requires a few steps:

Create the configuration file

Create the file ./config/auth0.yml within your application directory with the following content:

  auth0_domain: <YOUR_DOMAIN>
  auth0_client_id: <YOUR_CLIENT_ID>
  auth0_client_secret: <YOUR AUTH0 CLIENT SECRET>

Create the initializer

Create a new Ruby file in ./config/initializers/auth0.rb to configure the OmniAuth middleware:

AUTH0_CONFIG = Rails.application.config_for(:auth0)

Rails.application.config.middleware.use OmniAuth::Builder do
    callback_path: '/auth/auth0/callback',
    authorize_params: {
      scope: 'openid profile'

Create the callback controller

Create a new controller ./app/controllers/auth0_controller.rb to handle the callback from Auth0.

You can also run rails generate controller auth0 callback failure logout --skip-assets --skip-helper --skip-routes --skip-template-engine to scaffold this controller for you.

# ./app/controllers/auth0_controller.rb
class Auth0Controller < ApplicationController
  def callback
    # OmniAuth stores the information returned from Auth0 and the IdP in request.env['omniauth.auth'].
    # In this code, you will pull the raw_info supplied from the id_token and assign it to the session.
    # Refer to for complete information on 'omniauth.auth' contents.
    auth_info = request.env['omniauth.auth']
    session[:userinfo] = auth_info['extra']['raw_info']

    # Redirect to the URL you want after successful auth
    redirect_to '/dashboard'

  def failure
    # Handles failed authentication -- Show a failure page (you can also handle with a redirect)
    @error_msg = request.params['message']

  def logout
    # you will finish this in a later step

Add routes

Finally, add the following routes to your ./config/routes.rb file:

Rails.application.routes.draw do
  # ..
  get '/auth/auth0/callback' => 'auth0#callback'
  get '/auth/failure' => 'auth0#failure'
  get '/auth/logout' => 'auth0#logout'

Logging in

To redirect your users to Auth0 for authentication, redirect your users to the /auth/auth0 endpoint of your app. One way to do this is to use a link or button on a page:

<%= button_to 'Login', '/auth/auth0', method: :post %>
