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?

Hi Product Hunt! 👋
I’m Erwann. I spent several years building large-scale notification systems.
One thing always bothered me, phone verification hasn’t changed much in years:
• Users receive an SMS.
• They wait.
• They copy a code.
• They switch back to your app.
It works. Sometimes.
But it creates friction.
So I built Phone Verif:
Instead of receiving an OTP, users tap a “WhatsApp Connect” button:
• A pre-filled message opens
• They send it
• Their phone number is verified
No phone numbers or code to type.
No copy & paste.
Just a familiar WhatsApp flow.
Why Phone Verif?
⚡ Fast verification process
💸 Lower costs than SMS
🛠️ Simple API
🔐 Great for sign-up, login and 2FA

This would solve such a big pain for us... How does pricing compare to traditonal SMS OTP ?
Thanks @nick_keller 🤗
In most cases, you can divide your bill by 3
SMS costs are crazy these days, it will sure save us money. Will definitely try it on my app.

congrats on shipping this looks like an absolute lifesaver for mobile web onboarding flows where SMS drop-off is high.
Thanks @istiakahmad 🤗
That's exactly the goal
