Adding two-factor authentication is an excellent way to reduce fraud and increase trust from your users. This quickstart guides you through building a Java Servlets and AngularJS application that restricts access to a URL. Four Authy API channels are demoed: SMS, Voice, Soft Tokens and Push Notifications.

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 Authentication. 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 before sourcing it.
In Windows, set the
ACCOUNT_SECURITY_API_KEY variable manually.
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!
