How It Works
1
Scan QR Code
Open WhatsApp Business → tap ⋮ → Linked Devices → Link a Device → scan the QR above.
2
Session Saved
Your authentication token is saved locally. The server maintains the live session automatically — you can close this page.
3
OTPs Sent Directly
When a user logs in, the OTP is sent from your personal/business phone. No Twilio. No third-party SMS. No cost per message.
4
KFUPM Priority Routing
@kfupm.edu.sa emails exclusively use this gateway. No VPS fallback — the OTP will only arrive via this direct link.

Important Rules
- Keep your linked phone powered on and connected to internet — when the phone dies, the gateway drops.
- Rate limit: 1 OTP per phone number per 90 seconds (built in to prevent abuse).
- Do not use a personal number that you actively chat on — use a dedicated WhatsApp Business account.
- "Fresh Link" erases the saved session — use only if you switch phones or get "connection refused" after 5 reconnects.
