Twilio Verify Phone Verification Ruby on Rails Quickstart

Phone Verification is an important, high-confidence step in a registration flow to verify that a user has the device they claim to have. Adding Twilio Verify phone verification to your application will greatly reduce your number of fraudulent registrations and protect future application users from having their numbers registered by scammers.

This quickstart guides you through creating a RubyRails and AngularJS app that requires a phone verification step to create an account. Two channels of Phone Verification are demoed:

  • SMS
  • Voice

Sign Into or Create a Twilio Account

Either sign up for a free Twilio trial, or sign into an existing Twilio account.

Create a New Account Security Application

Once logged in, visit the Authy Console. Click on the red 'Create New Aplication' (or big red plus ('+') if you already created one) to create a new Authy application then name it something memorable.

Authy create new application

Twilio will redirect you to the Settings page next:

Account Security API Key

Click the eyeball icon to reveal your Production API Key, and copy it somewhere safe. You will use the API Key during the application setup step below.

Clone and Setup the Verification Application

Start by cloning our Ruby on Rails repository. Enter the directory and use bundle to install all of our dependencies:

bundle install
  1. Open the file config/application.example.yml
  2. Change ACCOUNT_SECURITY_API_KEY to the API Key from the above step
  3. Now, save the file as config/application.yml

If your file is saved as config/application.yml, the server will load it automatically as it starts up.

Language
ACCOUNT_SECURITY_API_KEY: YOUR APP_KEY
Enter the API Key from the Authy console and optionally change the port.
Enter an Application API Key

Enter the API Key from the Authy console and optionally change the port.

Next, create the tables:

bin/rails db:migrate

And then... actually, that's all the setup you'll need.

Now, launch the application with:

rails server

Assuming your API Key is correctly entered, you'll soon get a message that the app is up!

Use the Ruby on Rails Verify Phone Verification Demo

Keeping your phone at your side, vist the Phone Verification page of the demo at http://localhost:3000/verification/

Enter a Country Code and Phone Number, then choose which channel to request verification over, 'SMS' or 'CALL' (Voice). Finally, hit the blue 'Request Verification' button and wait.

Phone Verification by SMS or Voice

You won't be waiting long - you'll receive a phone call or SMS with the token. If you requested a phone call, as an additional security feature you may need to interact to proceed (enter a number on the phone keypad).

This function allows you to send the verification code over SMS or Voice depending on the 'via' variable.
Send a Phone Verification via SMS or Voice

This function allows you to send the verification code over SMS or Voice depending on the 'via' variable.

Either way you request the passcode, enter the token into the Verification entry form and click 'Verify Phone':

This function verifies the token for a user delivered over the Voice or SMS channel.
Verify a Token

This function verifies the token for a user delivered over the Voice or SMS channel.

And with that, your demo app is protected with Twilio's Verify! You can now log out to try the other channel.

What's Next?

Your demo app is now keeping fraudulent users from registering with your business and polluting the database. Next, check out all of the variables and options available to you in the Verify API Reference. For protecting your customers in an ongoing manner (with this same codebase) try the Ruby on Rails Authy Two-Factor Authentication Quickstart.

After that, take a stroll through the Docs for more Account Security demos and tutorials - as well as sample web applications using all of Twilio's products.
