Send OTP codes via WhatsApp

WhatsApp offers an authentication model format dedicated to sending OTPs, with standardized content imposed by Meta (not customizable beyond the code and validity period) to prevent phishing.

Available features

• Copy code button in one tap
• Autofill on recent Android and iOS, without user action
• Enhanced security: authentication messages are only delivered to the recipient's primary device, never to linked devices

Automatic SMS fallback

We recommend configuring an automatic fallback to SMS: if the WhatsApp OTP message is not delivered (number not registered on WhatsApp, network failure) within a defined period, EnvoiSMS.ma can automatically resend the code by classic SMS, ensuring that your user always receives their code.
