This technical workshop covered OTP as a latency-sensitive system: routing for speed, building an automatic WhatsApp-to-SMS-to-voice fallback chain, instrumenting verification completion as the metric that matters, and defending against OTP-pumping and interception fraud. It was aimed at engineers and security teams at banks, fintechs, and high-traffic consumer platforms. ## On the agenda - OTP latency as a conversion metric - Multi-channel fallback chains - SMS Retriever & autofill integration - OTP-pumping & traffic-pumping fraud - Verification funnel instrumentation ## Details **When** 20 August 2026 **Where** Riyadh, Saudi Arabia **Status** Took place **Format** In person **Duration** 1 day **Country** Saudi Arabia **Speaker** BroadNet Engineering · Platform Engineering ## Following up on Securing OTP at Scale — Latency, Fallback & Fraud The areas that match this event's agenda and audience, with the full product detail for each if you want to pick up where the conversation left off. - OTP API One-time passcodes for sign-up, login and payments, with automatic fallback to voice, WhatsApp or email so users still get their code when a channel fails.
