WhatsApp OTP: How to Send OTP on WhatsApp?

WhatsApp has become an indispensable part of our daily communication. From catching up with friends to handling work, it’s a platform that keeps us connected. Now, businesses are leveraging WhatsApp for sending One-Time Passwords (OTPs) – a crucial tool for enhancing security and user verification. In this article, we’ll explore the ins and outs of sending OTPs on WhatsApp, including various methods, benefits, and practical use cases. So, let’s dive in!

Sending OTPs through WhatsApp is becoming increasingly popular due to the app's widespread use and user-friendly interface. Unlike traditional SMS, WhatsApp OTPs offer enhanced security, higher delivery rates, and interactive features. Whether you are a business aiming to improve customer verification or an individual seeking a secure method to validate user identity, WhatsApp OTPs can be the ideal solution. This guide will walk you through everything you need to know about sending OTPs on WhatsApp effectively.

How to Send OTP via WhatsApp

If you’re looking to send OTPs, there are two ways to do it. You can send OTPs from your dedicated number, which is exclusively assigned to your business. This method allows for consistent branding and greater control over your communications, ensuring that your customers recognize and trust messages from your number. Alternatively, you can opt to send OTPs from a shared number used by multiple businesses. This approach is typically more cost-effective and simpler to set up, as it leverages a common infrastructure provided by your WhatsApp Business API service provider.

It’s always good to consider both options and choose the one that works best for you. A dedicated number might be the better choice for businesses seeking to establish a strong brand presence and maintain direct customer engagement. On the other hand, a shared number can be an efficient solution for smaller businesses or those looking to minimize costs while still benefiting from the robust security and high delivery rates offered by WhatsApp OTPs. Whichever method you choose, integrating WhatsApp OTP into your authentication process can significantly enhance security, convenience, and customer trust.

Sending OTP on WhatsApp Using a Shared Number
