Use Cases

Marketing AgenciesMarketing Agencies

An online user wants to participate in a contest posted on social media. You can’t just post the winner’s name, as this would compromise their personal identity. With Two Factor Authentication, you can send a PIN to the winner via a missed call with 100% accuracy and security.


Verifying a phone number on registration prevents bots from creating bulk accounts. This eradicates spam more effectively than captchas. Two Factor Authentication improves your app's security because your users enter a PIN that is sent to their phone every time they log in.


A customer has their phone number registered on a website and has opted-in to use missed call-based Two Factor Authentication. The customer completes their money transfer. The site then generates an authentication missed call to the user’s phone with a unique PIN.
