One-time Password (OTP) Provider Marketplace

Reliable & Secure Transactional SMS & Voice One-time Password (OTP) Provider Marketplace

RingCaptcha OTP Provider Marketplace

As a one-time password, OTP (also known as one-time PIN) delivery marketplace, we send SMS and voice OTP through many different providers ranging from big global ones like Twilio, Infobip, Nexmo, MessageBird, etc., to regional reliable ones like Cequens, Plivo, Bandwidth, etc.

Goals of OTP Provider Marketplace

  • Match customers with providers at the price and reliability desired
  • Increase the OTP reliability and robustness


The Technology Behind OTP Provider Marketplace

  • The first OTP is sent through the most reliable route
  • The second OTP which can be manually requested by 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 it could be through a different medium (SMS or voice)
  • 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
  • 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. 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.
