Why use WhatsApp OTP?
Everything you need to know about migrating from legacy SMS to WhatsApp for modern authentication.
What is a WhatsApp OTP?
A WhatsApp OTP (One-Time Password) is a secure, randomly generated code sent directly to a user's WhatsApp app instead of a traditional SMS text message. Because WhatsApp is encrypted and doesn't rely on local telecom carriers, WhatsApp OTP delivery rates are significantly higher, more secure against SIM-swapping, and often much cheaper than SMS.
Is a WhatsApp OTP better than an SMS OTP?
Yes. Legacy SMS OTP delivery is notoriously unreliable due to carrier filtering, international routing issues, and network congestion. By using the WhatsApp API for your OTPs, you bypass telecom carriers entirely and send the code over Meta's internet infrastructure, resulting in near 100% deliverability worldwide.
Can I send bulk messages along with my OTPs?
Absolutely. OTP Edge is not just an OTP API; it is a full-featured WhatsApp API platform. After a user is verified via a WhatsApp OTP, you can use the same infrastructure to send bulk marketing messages, transactional alerts, and PDF invoices directly to their inbox.
