In today’s digital ecosystem, one-time passwords (OTPs) are essential for authentication—whether for user registration, account recovery, or transaction verification. While SMS OTPs have been a traditional go-to method, they are increasingly vulnerable to security threats and delivery issues.
That’s where WhatsApp OTP steps in—and with chatalog.ai, businesses can harness the power of WhatsApp to deliver secure, encrypted OTPs with unparalleled reliability and user convenience.
Why Send OTP on WhatsApp?
Unlike SMS, which operates on outdated infrastructure and lacks encryption, WhatsApp messages are end-to-end encrypted, making it a highly secure channel for delivering OTPs. With over 2 billion users globally, WhatsApp is also a platform your customers are already familiar with and trust.
chatalog.ai enables businesses to deliver OTPs instantly via WhatsApp, providing a seamless, secure, and scalable solution tailored for modern customer engagement.
