QRSO
LiveWhatsApp · Authentication
Login & number verification via WhatsApp QR scan — no SMS cost, no OTP delay.
Visit: qrso.adiastra.id ↗01 / Context
SMS OTPs are costly and often late, while nearly every Indonesian user has WhatsApp. Verifying a number should be as simple as one scan.
02 / What we built
- ■ Auth session API: your app shows a QR, user scans → WhatsApp opens pre-filled → tap send
- ■ Your app receives the verified number + name + profile photo via real-time SSE or HMAC-SHA256 callbacks
- ■ Two modes: "auth" (login) and "verify" (capture number)
- ■ Brute-force protection and per-app rate limiting
03 / Architecture
Your app QRSO API QR scan WhatsApp message SSE / callback → verified
