OTP delivery best practices for apps and portals
Reduce failed verification journeys with smarter delivery logic, fallback channels, and cleaner reporting.
OTP delivery needs speed, reliability, and fallback logic.
Teams should define primary channels, backup channels, retry rules, and reporting events before scale increases.
- Use SMS for broad reach.
- Use WhatsApp or voice as backup where needed.
- Track sent, delivered, failed, and verified events.
