SMS OTP creates friction and costs money every time you send a code. Phone-Verif flips the flow. Users don’t receive an OTP. They tap a pre-filled WhatsApp message and send an authentication token instead. That proves ownership of their phone number. Because verification is user-initiated, repeat logins and 2FA aren’t billed per attempt. Lower costs. Less friction. A familiar user experience. What if phone verification didn’t require sending an OTP?
