Authenticate customers with WhatsApp OTPs

To optimize this process, it’s essential to balance security with usability. Implementing multi-factor authentication (MFA) adds an extra layer of protection by requiring users to provide multiple forms of verification, such as a password and a one-time code sent via WhatsApp. Offering various verification methods, including biometric authentication and document scanning, allows users to choose the option that best suits their preferences and devices.

Secure your customers’ information and prevent attacks by enforcing OTP verification during login

The WhatsApp Business API encrypts all messages, meaning only the customer can view the message. This makes WhatsApp a more reliable channel to send OTPs on and lowers the chance of hackers getting their hands on both a password and an OTP.
