As of November 2022, Twilio no longer provides support for Authy SMS/Voice-only customers. Customers who were also using Authy TOTP or Push prior to March 1, 2023 are still supported. The Authy API is now closed to new customers and will be fully deprecated in the future.
For new development, we encourage you to use the Verify v2 API.
Existing customers will not be impacted at this time until Authy API has reached End of Life. For more information about migration, see Migrating from Authy to Verify for SMS.
Adding Two-factor Authentication to your application is the easiest way to increase security and trust in your product without unnecessarily burdening your users. This quickstart guides you through building a Ruby and Ruby on Rails application that restricts access to a URL. Four Authy API channels are demoed: SMS, Voice, Soft Tokens and Push Notifications.
Ready to protect a tiny app from malicious hackers?
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.
You'll automatically be transported to the Settings page next. Click the eyeball icon to reveal your Production API Key.
Copy your Production API Key to a safe place, you will use it during application setup.
This Two-factor Authentication demos two channels which require an installed Authy Client to test: Soft Tokens and Push Notifications. While SMS and Voice channels will work without the client, to try out all four authentication channels download and install Authy Client for Desktop or Mobile:
Clone our repository locally, then enter the directory. Install all of the necessary ruby modules:
Next, open the file
config/application.example.yml. There, edit the
ACCOUNT_SECURITY_API_KEY, pasting in the API Key from the above step (in the console), and save the file as
It will be loaded when the application begins.
Once you have added your API Key, you are ready to run! Launch Rails with:
If your API Key is correct, you should get a message your new app is running!
With your phone (optionally with the Authy client installed) nearby, open a new browser tab and navigate to
Enter your information and invent a password, then hit 'Register'. Your information is passed to Twilio (you will be able to see your user immediately in the console), and the application is returned a
Now visit http://localhost:3000/login/ and login. You'll be presented with a happy screen:
If your phone has the Authy Client installed, you can immediately enter a Soft Token from the client to Verify. Additionally, you can try a Push Authentication simply by pushing the labeled button.
If you do not have the Authy Client installed, the SMS and Voice channels will also work in providing a token. To try different channels, you can logout to start the process again.
And there you go, Authy two-factor authentication is on and your Rails app is protected!
Now that you are keeping the hackers out of this demo app using Twilio Authy two-factor authentication, you can find all of the detailed descriptions of options and API calls in our Authy API Reference. If you're also building a registration flow, also check out our Verify product and the Ruby Phone Verification quickstart which uses this codebase.
