• Currently only support mobile phones with US country codes
• Removed Onetouch support
• Removed ability to request a phone call

• Swap out devise-authy in your Gemfile with devise-twilio-verify
• `gem 'devise-twilio-verify'
• Setup a Twilio Verify account
• Add env vars and/or Rails credentials for:
  • TWILIO_AUTH_TOKEN
  • TWILIO_ACCOUNT_SID
  • TWILIO_VERIFY_SERVICE_SID
• Create/run a migration to rename and add the following columns

    class MigrateAuthyToTwilioVerify < ActiveRecord::Migration[6.1]
      def change
        rename_column :users, :authy_sms, :twilio_verify_sms
        rename_column :users, :authy_enabled, :twilio_verify_enabled
        rename_column :users, :last_sign_in_with_authy, :last_sign_in_with_twilio_verify
        add_column :users, :twilio_totp_factor_sid, :string
      end
    end

• you can also delete the users.authy_id column if you choose
• Twilio Verify service sms will be sent to users.mobile_phone, so make sure you store the users 2fa phone number in this column, can make this field name dynamic in the future
• Do a project code wide search & replace of these terms
  • devise-authy -> devise-twilio-verify
  • authy_ -> twilio_verify_
  • _authy -> _twilio_verify
  • authy- -> twilio-verify-
  • -authy -> -twilio-verify
  • Authy -> TwilioVerify
• Do a project file search & replace of any file with authy in the name (here's a few examples to replace)
  • app/javascript/src/deviseTwilioVerify.js
  • app/assets/stylesheets/devise_twilio_verify.scss
  • config/locales/devise.twilio_verify.en.yml

This is a Devise extension to add Two-Factor Authentication with Twilio Verify to your Rails application.

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

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

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

$ export TWILIO_AUTH_TOKEN=YOUR_TWILIO_AUTH_TOKEN
$ export TWILIO_ACCOUNT_SID=YOUR_TWILIO_ACCOUNT_SID
$ export TWILIO_VERIFY_SERVICE_SID=YOUR_TWILIO_VERIFY_SERVICE_SID

Next add the gem to your Gemfile:

gem 'devise'
gem 'devise-twilio-verify'

And then run bundle install

Add Devise Twilio Verify to your App:

rails g devise_twilio_verify:install

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

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

Run the following command:

rails g devise_twilio_verify [MODEL_NAME]

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

Add :twilio_verify_authenticatable and :twilio_verify_lockable to the devise options in your Devise user model:

devise :twilio_verify_authenticatable, :twilio_verify_lockable, :database_authenticatable, :lockable

(Note, :twilio_verify_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 DeviseTwilioVerifyAddToUsers < ActiveRecord::Migration[6.0]
  def self.up
    change_table :users do |t|
      t.string    :authy_id
      t.datetime  :last_sign_in_with_twilio_verify
      t.boolean   :twilio_verify_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_twilio_verify, :twilio_verify_enabled
    end
  end
end

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_twilio_verify => "/verify-token",
	:enable_twilio_verify => "/enable-two-factor",
	:verify_twilio_verify_installation => "/verify-installation"
}

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

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

app/views/devise/devise_twilio_verify/enable_twilio_verify.html.erb
app/views/devise/devise_twilio_verify/verify_twilio_verify.html.erb
app/views/devise/devise_twilio_verify/verify_twilio_verify_installation.html.erb

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

class MyCustomModule::DeviseTwilioVerifyController < Devise::DeviseTwilioVerifyController

  protected
    def after_twilio_verify_enabled_path_for(resource)
      my_own_path
    end

    def after_twilio_verify_verified_path_for(resource)
      my_own_path
    end

    def after_twilio_verify_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_twilio_verify: 'my_custom_module/devise_twilio_verify'}

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

config/locales/devise.twilio_verify.en.yml

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}_twilio_verify_token_checked"]

# Eg.
session["user_twilio_verify_token_checked"]

Twilio Verify 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-twilio-verify by modifying the Devise config file config/initializers/devise.rb and adding the configuration:

config.twilio_verify_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 @twilio_verify_qr_code.

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 Twilio Verify Devise demo app:

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

Run the following command:

$ bundle exec rspec
