🚨🚨🚨

This library is no longer actively maintained.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.

Coming soon: Look out for a new Devise plugin to use Twilio Verify with Devise

Pre-requisites

To use the Authy API you will need a Twilio Account, sign up for a free Twilio account here.

Create an Authy Application in the Twilio console and take note of the API key.

Demo

See this repo for a full demo of using authy-devise.

Getting started

First get your Authy API key from the Twilio console. We recommend you store your API key as an environment variable.

$ export AUTHY_API_KEY=YOUR_AUTHY_API_KEY

Next add the gem to your Gemfile:

gem 'devise'
gem 'devise-authy'

And then run bundle install

Add Devise Authy to your App:

rails g devise_authy:install

--haml: Generate the views in Haml
--sass: Generate the stylesheets in Sass

Configuring Models

You can add devise_authy to your user model in two ways.

With the generator

Run the following command:

rails g devise_authy [MODEL_NAME]

To support account locking (recommended), you must add :authy_lockable to the devise :authy_authenticatable, ... configuration in your model as this is not yet supported by the generator.

Manually

Add :authy_authenticatable and :authy_lockable to the devise options in your Devise user model:

devise :authy_authenticatable, :authy_lockable, :database_authenticatable, :lockable

(Note, :authy_lockable is optional but recommended. It should be used with Devise's own :lockable module).

Also add a new migration. For example, if you are adding to the User model, use this migration:

class DeviseAuthyAddToUsers < ActiveRecord::Migration[6.0]
  def self.up
    change_table :users do |t|
      t.string    :authy_id
      t.datetime  :last_sign_in_with_authy
      t.boolean   :authy_enabled, :default => false
    end

    add_index :users, :authy_id
  end

  def self.down
    change_table :users do |t|
      t.remove :authy_id, :last_sign_in_with_authy, :authy_enabled
    end
  end
end

Final steps

For either method above, run the migrations:

rake db:migrate

[Optional] Update the default routes to point to something like:

devise_for :users, :path_names => {
	:verify_authy => "/verify-token",
	:enable_authy => "/enable-two-factor",
	:verify_authy_installation => "/verify-installation",
	:authy_onetouch_status => "/onetouch-status"
}

Now whenever a user wants to enable two-factor authentication they can go to:

http://your-app/users/enable-two-factor

And when the user logs in they will be redirected to:

http://your-app/users/verify-token

Custom Views

If you want to customise your views, you can modify the files that are located at:

app/views/devise/devise_authy/enable_authy.html.erb
app/views/devise/devise_authy/verify_authy.html.erb
app/views/devise/devise_authy/verify_authy_installation.html.erb

Request a phone call

The default views come with a button to force a request for an SMS message. You can also add a button that will request a phone call instead. Simply add the helper method to your view:

<%= authy_request_phone_call_link %>

Custom Redirect Paths (eg. using modules)

If you want to customise the redirects you can override them within your own controller like this:

class MyCustomModule::DeviseAuthyController < Devise::DeviseAuthyController

  protected
    def after_authy_enabled_path_for(resource)
      my_own_path
    end

    def after_authy_verified_path_for(resource)
      my_own_path
    end

    def after_authy_disabled_path_for(resource)
      my_own_path
    end

    def invalid_resource_path
      my_own_path
    end
end

And tell the router to use this controller

devise_for :users, controllers: {devise_authy: 'my_custom_module/devise_authy'}

I18n

The install generator also copies a Devise Authy i18n file which you can find at:

config/locales/devise.authy.en.yml

Session variables

If you want to know if the user is signed in using Two-Factor authentication, you can use the following session variable:

session["#{resource_name}_authy_token_checked"]

# Eg.
session["user_authy_token_checked"]

OneTouch support

To enable Authy push authentication, you need to modify the Devise config file config/initializers/devise.rb and add configuration:

config.authy_enable_onetouch = true

Generic authenticator token support

Authy supports other authenticator apps by providing a QR code that your users can scan.

To use this feature, you need to enable it in your Twilio Console

Once you have enabled generic authenticator tokens, you can enable this in devise-authy by modifying the Devise config file config/initializers/devise.rb and adding the configuration:

config.authy_enable_qr_code = true

This will display a QR code on the verification screen (you still need to take a user's phone number and country code). If you have implemented your own views, the QR code URL is available on the verification page as @authy_qr_code.

Rails 5 CSRF protection

In Rails 5 protect_from_forgery is no longer prepended to the before_action chain. If you call authenticate_user before protect_from_forgery your request will result in a "Can't verify CSRF token authenticity" error.

To remedy this, add prepend: true to your protect_from_forgery call, like in this example from the Authy Devise demo app:

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception, prepend: true
end

Running Tests

Run the following command:

$ bundle exec rspec

Notice: Twilio Authy API’s Sandbox feature will stop working on Sep 30, 2021

Twilio is discontinuing the Authy API’s Sandbox, a feature that allows customers to run continuous integration tests against a mock Authy API for free. The Sandbox is no longer being maintained, so we will be taking the final deprecation step of shutting it down on September 30, 2021. The rest of the Authy API product will continue working as-is.

This repo previously used the sandbox API as part of the test suite, but that has been since removed.

You will only be affected if you are using the sandbox API in your own application or test suite.

For more information please read this article on how we are discontinuing the Twilio Authy sandbox API.
