Step up your security with these WhatsApp OTP benefits
Using WhatsApp as a verification channel can bring great benefits to your business and your customers.
Ensure a best-in-class authentication experience
The digital landscape has increased the number of touchpoints a customer has during their journey. With the increase of fraud and security threats, authentication is key to keep your customers’ information secure. You can prevent attacks by enforcing OTP verification at different stages of the customer journey.
The WhatsApp Business API encrypts all messages, so that only the customer can view the message. This makes WhatsApp a more reliable channel to send OTPs on and decreases the chance of bad actors getting access to both a password and an OTP. In some markets, WhatsApp OTP can help you reduce your messaging costs. Reach out to us for more information and pricing and double up on security today!
