Securing OTP at Scale — Latency, Fallback & Fraud
A technical workshop for teams running high-volume one-time-passcode flows — building fast, resilient, multi-channel OTP delivery that converts and resists abuse.
About this event
A one-time passcode that arrives late, or not at all, is a failed login. 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
