Delivers one-time passwords and login codes over WhatsApp for sign-ups, logins, and transaction verification. Gives users a faster, higher-engagement alternative to SMS codes on a channel they already trust.
Your app or store requests an OTP when a user signs up, logs in, or verifies a transaction.
Defuser delivers the code using an Authentication-category template to the user's verified number.
The user enters the code and your system confirms it, completing the secure action.
Many businesses see better delivery and read rates on WhatsApp because messages arrive in an app users actively check. Authentication templates are purpose-built by Meta for sending codes.
OTPs use WhatsApp's Authentication conversation category. Defuser's transparent calculator shows the per-conversation fee for each of 30+ countries so you can budget accurately.
Defuser uses the official WhatsApp Business API with its template-approval process, and you decide exactly which automated messages go out and what information they contain. Authentication and utility templates are designed for transactional use, and anything sensitive can always route to your trained staff.
