Summary

One-time passcode verification is presented as essential for secure onboarding, transactions, and account recovery, but SMS-only delivery can fail because of network, international, or signal issues, causing user frustration and abandoned processes. Dynamic OTP fallbacks address this by automatically shifting among channels such as SMS, WhatsApp, email, and voice calls based on delivery status, timing, user preferences, cost, geographic conditions, and risk signals. The approach can improve completion and conversion rates, reduce delivery costs, and strengthen fraud prevention when paired with real-time phone intelligence that detects disposable, virtual, or suspicious numbers. Didit positions its AI-native modular identity platform as a solution for configuring these workflows through APIs or a no-code console, combining phone and email verification with risk-based steps such as ID verification, liveness checks, face matching, and AML screening. The platform also advertises Free Core KYC, no setup fees, and pay-per-successful-check pricing to support scalable automated verification journeys.
