What Is It?
What is WhatsApp WiFi login, and why does it matter?
A captive portal is the login screen that appears when you connect to public WiFi. Instead of asking guests to type an email or wait for an SMS, WhatsApp login uses the app 2+ billion people already have open, eliminating friction and capturing a more valuable verified contact.
How it works: step by step
01
Guest connects to venue WiFi
Device detects the access point and attempts internet access. AP intercepts traffic.
02
Branded captive portal appears
A white-labeled splash page opens automatically. Fully branded under your client's identity.
03
Guest taps "Login with WhatsApp"
They enter their phone number, the same one linked to their WhatsApp account.
04
OTP sent to their WhatsApp
A 6-digit one-time code arrives as a WhatsApp message within 3 seconds. No SMS, no carrier fees.
05
Internet access granted
Verification complete. Guest profile created and stored in your dashboard. Full internet unlocked.

Technical Overview
How WhatsApp OTP authentication works on a captive portal
Four steps from device connection to verified guest profile — all handled by the platform, invisible to the reseller.
01
Guest device connects to AP → captive portal opens
Access point intercepts HTTP traffic and redirects to the branded captive portal. Works on all major AP vendors: Ubiquiti, Cisco Meraki, Aruba, Cambium, TP-Link Omada, and 15+ more.
02
Guest taps WhatsApp login → platform sends OTP via WhatsApp Business API
Guest enters phone number. MyWiFi platform calls the WhatsApp Business API to dispatch a 6-digit OTP as a WhatsApp message. No SMS charges, no carrier dependency.
03
Guest enters 6-digit OTP → verified
OTP validated server-side with a 10-minute expiry and single-use enforcement. Failed attempts are rate-limited to prevent abuse. No session persists until verification passes.
04
Platform captures profile data → grants internet access
Verified phone number, WhatsApp ID, visit timestamp, and device metadata stored in the reseller's white-label dashboard. MAC-based session established. Guest gets full internet access.

Pitch in markets where WhatsApp is the default
Brazil, Mexico, India, the Middle East. Markets where WhatsApp has replaced SMS entirely. When a client in São Paulo asks about WiFi marketing, you can offer WhatsApp OTP login — a capability that opens doors other pitches can't.
Higher conversion
WhatsApp OTP converts at a higher rate than SMS in dominant markets
In markets where WhatsApp dominates, SMS messages are often ignored or filtered. WhatsApp messages get opened. A WiFi login via WhatsApp feels natural. Guests complete it faster, with less drop-off, producing a better opt-in than legacy methods.
