This article was updated on December 15, 2023

Customers all over the globe are using phone numbers to quickly establish identity and provide security to their applications and platforms. Vonage has made it even easier — and you can now access this powerful tool!

Simplifying Two-Factor Authentication

At Vonage, we help hundreds of businesses send millions of 2FA requests in all major regions, including North and South America, Europe, and Asia.

Our customers tell us they’re aware of the multitude of authentication options available — from less expensive options like email to more expensive (and more complex) soft tokens, SDKs, and even hard tokens like physical key fobs.

But there’s one simple, easy-to-use API that removes the complexity of 2FA at a global scale. Our turnkey Verify API can be tested in a matter of minutes and scaled globally in just hours.

We’re excited to announce Verify V2 is now available! We’ve been working hard to enhance Verify V2, making it an even more powerful two-factor authentication tool for developers and businesses. To get started, simply refer to the developer documentation.

New Channels for Authentication

Verify V2 offers both a streamlined user experience and superior fraud protection. There are new paths to user authentication, in addition to the current SMS and voice (TTS) channels.

WhatsApp

With more than 2.2 billion active users, WhatsApp is a popular channel all over the world, connecting people over a basic internet connection and serving as a great primary or secondary channel to SMS. WhatsApp has also proven itself to be a secure way to authenticate end-users, which is why we have added WhatsApp as a channel for Verify V2.

The WhatsApp channel integrates seamlessly into our channel lineup for delivering one-time passwords (OTPs). WhatsApp differentiates the end-user experience because it can work on both cellular data or wi-fi. This improves your application’s conversion rate since you don’t have to worry about network congestion like you normally would with SMS. To use WhatsApp with Verify V2, you must have your own WhatsApp Business Account (WABA), which Vonage can help configure—improving your brand recognition over WhatsApp.

Email

Email is available as an additional verification channel to supplement SMS, voice, and WhatsApp. Whenever a user is unable to verify using their phone, an OTP can be sent to their email address in order to authenticate, providing even more flexibility. Customers have the option to integrate their own email domain within the email channel as part of Verify V2.

Silent Authentication

Looking for a more secure and frictionless authentication experience? Our new Silent Authentication channel (currently in the Alpha product phase) is designed to be more secure while also improving the overall end-user experience. 

With only a phone number, Silent Authentication validates a user in seconds through a mobile data connection. This increases overall conversions and encourages more time spent on your platform.

Silent Authentication also addresses the security risks associated with social engineering schemes that intercept OTPs. Silent Authentication completely prevents this type of fraud, with no OTP being delivered.

With Verify V2, you can use Silent Authentication as your primary verification channel and customize automatic failover to other channels — SMS, voice, WhatsApp, or email — when needed.

Fraud Protection

The threat of fraudulent traffic is a constant issue, but the new Verify V2 Anti-Fraud System protects customers using the latest security features. The system runs semi-autonomously by monitoring customers' networks and takes action when it detects unusual traffic, protecting businesses from toll fraud. If a network block occurs and SMS or voice is not available, the additional Verify V2 authentication channels, such as WhatsApp or email, will function as normal. When safe, customers can easily use self-service to restore their networks using the Network Unblock API.

Improved Product Flexibility

Developers can now control how one-time passcodes are delivered using the "type" and "number" strings within the "to" array of Verify V2. This means applications can deploy 2FA in a manner that best suits end-users' preferences. 

Event and summary callbacks have been added, allowing for a multitude of integration and customization opportunities. Webhooks can be configured using applications from the customer dashboard related to Verify requests, which will display information such as failed, completed, or expired. In addition, when fraudulent activity is detected and a network block occurs, a callback provides information on the blocked status and the reason.

Pricing

Verify V2 is available for use with the Verify Conversion pricing model. This model only changes for successful verifications, plus messaging and voice rates. You will also have the option to generate and manage your own PIN code. The simplified Verify Success pricing model provides you with 1 all-in charge for successful verifications.
