Why send OTPs on WhatsApp
Most of your users already have WhatsApp open on their phone. Sending the login or sign-up code there means it arrives in an app they trust, from your business name, instead of a random SMS sender. For apps with users across countries, it also avoids juggling a different SMS route for every market.
You stay in control
The number, the WhatsApp Business account and your user data stay in your business's name. You get a written scope before work starts and talk directly with the engineers doing the integration.
