Have you ever received an OTP or one-time password through SMS to check a transaction or log in? Most people think that is the safest method, but they are unaware that SMS OTP authentication is not as secure as they believe.

Luckily, Many companies are not changing to encrypted OTPs on WhatsApp for included security. So, you can now calm down knowing that your transactions and login are secure. By employing encrypted OTPs on WhatsApp, organizations can boost clients’ trust in their brand, ultimately leading to a positive client experience.

In this blog post, we will analyze the hidden facts of WhatsApp OTP and show you how to control the power of this renowned messaging application for a faster and simpler verification experience.

WhatsApp OTP vs SMS OPT

WhatsApp OTP and SMS OTP sound similar, but they have slightly different characteristics. Keep reading this blog to understand which points distinguish them.

SMS OTPs are forwarded over a cellular network. This network can be dangerous to interception and other attacks. WhatsApp OTPs are shared over the internet and are end-to-end encrypted. Only the sender and receiver can see the message.

Another difference between SMS OTPs and WhatsApp OTPs is their efficiency. SMS OTPs can be shared with any phone number, even if the user does not have WhatsApp installed. On the other hand, WhatsApp OTPs can only be forwarded to users who have WhatsApp installed.

Other features special to WhatsApp OTPs are unavailable on SMS, such as rich media content such as images and videos. This feature is helpful for companies that wish to send customized OTP messages to their clients.

What is the Prerequisite to Sending OTP on WhatsApp

Sending OTPs on WhatsApp isn’t as straightforward as using your account. There are a few hoops to jump through first, but they’ll ensure a secure and professional experience for you and your users. Here’s what you’ll need:

1. WhatsApp Business API Access

To begin, you must gain access to the WhatsApp Business API. Chatbot.team can facilitate this process by acting as a service provider that helps you get the necessary API permissions. This setup involves registering your business with the Chatbot.team, which will then handle the API integration and ensure you meet all requirements laid out by WhatsApp.

2. Create a WhatsApp Business Profile

Once you have API access, the next step is to make a WhatsApp Business Profile. This profile should have your business name, address, contact details, and a brief description. A complete and verified profile builds trust among users and confirms that they are interacting with a legitimate entity.

3. Prepare a WhatsApp Message Template

WhatsApp requires businesses to use pre-approved message templates to ensure keeping with its messaging policies when sharing OTPs. You must design your OTP message template and submit it for approval. An example template could be: “Your verification code. Please enter this code to proceed.” The template should avoid promotional content and focus solely on delivering the OTP.

4. Use the API to Share the Message

After your message template is approved, apply the WhatsApp Business API to forward the OTP. This involves programmatically generating a special OTP for every transaction, inserting it into the approved message template, and sending this message to the user’s WhatsApp number. The API call will specify the receiver’s phone number and the message content, including the OTP.

Benefits of Sending OTP on WhatsApp

Using WhatsApp as an alternative to SMS or email has many benefits, particularly when sending One-Time Passwords (OTPs). Companies have been steadily converting to WhatsApp as their go-to choice for authentication due to the following advantages.

Businesses can use the WhatsApp Business API to automate and personalize OTP messages with branding and customized details. This ability boosts the professionalism of the messages and can help improve brand recognition and trust.
