For new development, we encourage you to use the Verify API instead of the Authy API. The Verify API is an evolution of the Authy API with continued support for SMS, voice, and email one-time passcodes, an improved developer experience and new features including:
- Access via the Twilio CLI
- Improved Visibility and Insights
- Push authentication SDK embeddable in your own application
You are currently viewing the Authy API. The Authy API will continue to be maintained, but any new features and development will be on the Verify API. Check out the FAQ for more information and Verify API Reference to get started.
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 Java, Spring and AngularJS 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 big hacking efforts?
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 Java repository locally, then enter the directory. Install all of the necessary node modules:
Next, open the file
.env.example. There, edit the
ACCOUNT_SECURITY_API_KEY, pasting in the API Key from the above step (in the console), and save the file as
.env. Either source the .env file or otherwise set the
ACCOUNT_SECURITY_API_KEY in your environment.
Once you have added your API Key, you are ready to run! Launch the app with:
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:8080/login/index.html 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 Notification 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 Java app is protected!
Now that you are keeping the hackers out of this demo app using Two-factor Authentication with Twilio Authy, you can find all of the detailed descriptions for 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 phone verification quickstart which uses this codebase.
