As cybersecurity continues to be a top priority in the digital ecosystem, the methods businesses use to authenticate users are evolving. WhatsApp, a widely used messaging platform, has introduced a new solution for businesses to send one-time passcodes (OTPs) and verification codes through its Business Management API. This capability, now extended to India and other global markets, offers a secure and user-friendly way for businesses to verify their users, leveraging WhatsApp’s massive reach and trusted communication infrastructure.
How WhatsApp authentication templates work
WhatsApp’s authentication templates allow businesses to send OTPs to users directly via WhatsApp. These templates come in three types:
- One-tap autofill templates: When users receive an OTP via WhatsApp, they can tap a button to autofill the code into the corresponding app. However, it is currently only supported on Android devices and requires additional app integration.
- Copy code templates: Users receive an OTP alongside a button that allows them to copy the code to their clipboard. They can then paste the code into the corresponding app manually.
- Zero-tap templates: The most user-friendly option allows the OTP to be captured by the app automatically without any user interaction.
These templates are designed to be simple and effective, using fixed preset text to keep things clear and consistent. They also include optional features like security disclaimers and expiration warnings, further enhancing the security and authentication process.
The benefits of using WhatsApp authentication
WhatsApp authentication templates offer several key benefits including:
- Enhanced security: By sending OTPs directly to a user’s WhatsApp account, businesses can reduce the risk of phishing attacks or man-in-the-middle (MITM) attacks that are more common with traditional SMS-based authentication. WhatsApp’s end-to-end encryption ensures that these codes remain secure throughout the authentication process.
- Faster authentication: The streamlined process, particularly with the one-tap autofill and zero-tap options, allows users to authenticate quickly without the need for manual code entry.
- Wider reach: In markets like India, where WhatsApp has over 500 million users, integrating WhatsApp as an authentication channel ensures that businesses can reach a wide audience through a platform they already trust and use regularly.
