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 to your application to validate new accounts 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 Java, JDK, Servlets and AngularJS app that requires a Phone Verification step to create an account. Two channels of Phone Verification are demoed: SMS and Voice.
Ready to add Twilio Verify to a demo app and keep the bad actors away?
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.
Twilio will redirect you to the Settings page next:
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.
Start by cloning our Servlets repository. Enter the directory and use gradle to install all of our dependencies:
- Open the file
ACCOUNT_SECURITY_API_KEYto the API Key from the above step
- Now, save the file as
- Source the env file:
In Windows, set the
ACCOUNT_SECURITY_API_KEY variable manually.
That's all the setup you'll need.
Now, launch the application with:
Assuming your API Key is correctly entered, you'll soon get a message that the app is up!
Keeping your phone at your side, vist the Phone Verification page of the demo at http://localhost:8080/verification/
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.
You'll either receive a phone call or an SMS with the verification token. If you requested a phone call, as an additional security feature you may need to interact to proceed (enterg a number on the phone keypad).
Either way you requested the passcode, enter the token into the Verification entry form and click 'Verify Phone':
And with that, your demo app is protected with Twilio's Phone Verification! You can now log out to try the untried channel.
Your demo app is now keeping fraudulent users from registering with your business and polluting your database. Next, check out all of the variables and options available to you in the Phone Verification API Reference. Also, to protect your customers in an ongoing manner (with this same codebase) try the Java Servlets Authy Two-Factor Authentication Quickstart.
After that, visit the Docs for more Account Security demos and tutorials and web applications using all of Twilio's products.
