Businesses with an app on the Play Store or App store often struggle to get genuine users to signup.

So, in an attempt to attract only authentic users to their apps, many businesses have started offering referral credits and signup bonuses, especially in fintech. And as an added layer of security, these companies rely on verification channels like SMS OTP to authenticate the users during signups and logins.

While SMS OTPs have worked traditionally, but given the rise in fraudulent activities, it lacks the required security and UX to fight today’s security threats.

This is where ExoVerify’s nOTP solution comes to the rescue. With this revolutionary solution, Exotel tries to resolve both the security and UX challenges associated with SMS OTP in the most economical manner. And the good news is, you don’t have to completely say goodbye to your old buddy - SMS OTP.

Our ExoVerify solution comes packed with SMS OTP for people who still prefer the traditional approach and want to keep it as a backup mechanism in their verification process.

Who is it for?

  • Last-Mile Delivery Executives (Drivers/Delivery Agents) and 3PL Businesses
    • Integrate driver-side apps with nOTP and verify your drivers every day when they start work to ensure your customer’s goods are in the right hands.
    • With ExoVerify’s nOTP product, you ensure that only a registered driver/agent can verify himself through your app using the Verification Confirmation WebHook feature in ExoVerify. 
    • You can also verify the drivers silently in the background without even asking the driver to log out every day. This enhances the user’s verification experience without compromising security.
  • Fin-Tech Apps:
    • nOTP protects fraudulent signups in the fintech apps through  Device and SIM binding. This means users are only verified when their SIM is on the same device as their app. Their verification gets rejected if the app and SIM are found to be on two separate devices.
    • Weed out malicious numbers with the Verification Confirmation WebHook feature in ExoVerify. This feature cross-checks any incoming requests with your personal database of malicious numbers and blocks them before they can do any damage.
    • Our SDK and StatusCallBack Webhook make sure your users are always double-checked for accuracy, providing verification from both the front end and back end.
  • Cab Aggregators
    • Verify your riders and drivers as often as you need. Using Device and SIM Binding allow only registered driver to verify themself and ensures your customers are riding with the allotted driver partners.

It is just as applicable to the Gaming Industry and other industries with an driver/agent/service-provider/employee only App.

ExoVerify ensures OTPs that comply with your requirements(length, type, and TTL) are sent and validated securely, offloading the need to keep any intermediate server at your end to generate and manage OTPs. It also ensures that the SMS is sent in a highly reliable manner with low latencies.
