Technology Behind OTP Provider Marketplace

The goal of an OTP marketplace is to: (1) match customers with providers at the price and reliability desired, and (2) increase the OTP reliability and robustness. Here is how RingCaptcha achieves high reliability OTPs with a low cost for countries across the globe:

The First Request
The first OTP is sent through the most reliable route.
First OTP Request Isn't A Success
The second OTP can be manually requested by the user or sent by our auto follow-up feature, which triggers when a requested OTP is not used within a period of time, through an alternative provider route and even through a different medium (SMS or voice).
Manual OTP Request Options
Alternative out-of-band mechanisms, such ‘Dial-for-Help’, ‘AI Assist’, and ‘Human Touch’ can be triggered manually or automatically should the user still not receive her OTP.
Security Filters
Each OTP request passes through AI and heuristics powered security filters to ensure that it is valid and you are protected against various attacks and pranks.


Data-driven OTP Reliability

Our OTP marketplace has a unique vantage point—it enables us to measure the reliability and speed of different provider routes to discover the best routes for each region/country (see empirical reports comparing different providers in different continents/countries in the last section). This data enables us to mix-and-match primary and fallback routes/medium appropriately to provide the OTP reliability you demand at the price you desire. Furthermore, since we deliver SMS and voice OTP at large scale through multiple providers, you can enjoy competitive pricing because of our economies of scale.
