WhatsApp OTP allows businesses to authenticate customers by sending one-time passcodes (OTP) over WhatsApp. This method helps build trust and save money. Messaging apps like WhatsApp are extremely popular in some countries, making it a convenient channel for users to receive OTPs. With WhatsApp Authentication, businesses can offer customers the choice of receiving an OTP in the app they're already familiar with. The service ensures secure delivery with end-to-end encryption and global compliance, keeping customer accounts secure and enhancing user experience. By using WhatsApp as a verification channel, businesses can benefit from a branded and authentic business account, accompanied by a green badge, which verifies the account. WhatsApp's end-to-end encryption ensures that only the end user can view the delivered message, reducing potential spam and fraud attacks. The WhatsApp Business API encrypts all messages, making it a reliable channel to send OTPs and decreasing the chance of unauthorized access. Sinch provides the tools and support to get started with WhatsApp OTP, including setting up a Meta Business Manager account, signing up for a Sinch Dashboard account, and submitting message templates for approval.
