🚨🚨🚨

This demo is no longer actively maintained. The Authy API has been replaced with the Twilio Verify API. Twilio will support the Authy API through November 1, 2022 for SMS/Voice. After this date, we’ll start to deprecate the service for SMS/Voice. Any requests sent to the API after May 1, 2023, will automatically receive an error. Push and TOTP will continue to be supported through July 2023.

Learn more about migrating from Authy to Verify.

• Verify + Ruby (Rails) quickstart
• Twilio Ruby helper library
• Verify API reference

Please direct any questions to Twilio Support. Thank you!

Authy Devise Demo

This is a demo of using Devise and Authy together with the authy-devise gem to add two factor authentication to a Rails application.

Running this demo

This demo was built with Ruby 2.5.1, but should run with any Ruby version that is supported by Rails/Devise.

To run this application download or clone it from GitHub, change into the directory and install the dependencies:

git clone https://github.com/twilio/authy-devise-demo.git
cd authy-devise-demo
bundle install

Create and migrate the database:

rails db:create db:migrate

Get your Authy application API key from the Twilio console and set it in your environment variables:

Through CLI:

export AUTHY_API_KEY=YOUR_API_KEY

Or in .env:

cp .env{.example,}

Place API key in .env file generated from above command.

Run the Rails application:

rails server

Visit localhost:3000 and sign up as a new user.

Building this demo yourself

1. Create a new Rails application

   rails new authy-devise-demo
   cd authy-devise-demo

2. Generate a controller

   rails generate controller welcome index signed_in

3. Add a root path and signed in path to your config/routes.rb

   Rails.application.routes.draw do
     get "signed_in", to: "welcome#signed_in"
     root :to => 'welcome#index'
   end

4. Update the root and signed in views

   # app/views/welcome/index.html.erb
   <h1>Welcome to the sample app</h1>
   <p><%= link_to "Sign up", new_user_registration_path %></p>
   <p><%= link_to "Sign in", new_user_session_path %></p>

   # app/views/welcome/signed_in.html.erb
   <h1>Welcome to the sample app</h1>
   <p>You are signed in as <%= current_user.email %></p>

5. Add the devise and devise-authy gems to your Gemfile and install

   gem 'devise', '~> 4.5'
   gem 'devise-authy', '~> 1.9'

   bundle install

6. Install devise

   rails generate devise:install

7. Add flash messages to the app/views/layouts/application.html.erb and update the default URL options in config/environments/development.rb

   <p class="notice"><%= notice %></p>
   <p class="alert"><%= alert %></p>

   config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }

8. Generate a user model with Devise and migrate the database

   rails generate devise User
   rails db:migrate

9. Edit app/controllers/welcome_controller.rb and add:

   class WelcomeController < ApplicationController
     before_action :authenticate_user!, only: :signed_in
   
     def index
       redirect_to signed_in_path if user_signed_in?
     end
   
     def signed_in
     end
   end

10. Install authy-devise

    rails generate devise_authy:install

11. Open config/initializers/authy.rb and add your Authy API key (generate one in the Twilio Console)

    Authy.api_key = "YOUR_API_KEY"
    Authy.api_uri = "https://api.authy.com/"

12. Add authy-devise to the User model and run the resulting migration

    rails generate devise_authy User
    rails db:migrate

13. Run the server and visit http://localhost:3000/users/sign_up to create a user

    rails server

14. When signed in, visit http://localhost:3000/users/enable_authy to enable 2FA

15. Sign out and sign back in again and you will be required to enter your 2FA token
