What is guest WiFi authentication?
Guest WiFi authentication is the process of verifying a user's phone number with a one-time code before they get online. Instead of a shared password anyone can pass around, each guest is individually identified — which is what security and access-logging rules actually require. Useroam handles this over SMS or WhatsApp in a fast, guest-friendly flow.
SMS verification
The guest enters their phone number on the captive portal, receives a one-time code by SMS, confirms it and connects. Behind the scenes, the verified session is matched to the connection records and tracked from a central dashboard.
WhatsApp verification
WhatsApp verification delivers the same one-time code through WhatsApp instead. It can significantly cut SMS costs — especially with international guests, where SMS delivery is expensive and unreliable — and feels natural to anyone who already lives in WhatsApp.
Which method should you choose?
SMS reaches every phone; WhatsApp is faster and more economical at scale. Most venues do not have to choose: you can offer both side by side and let guests pick, matching your audience profile and operational needs.
Verification and logging with Useroam
Useroam combines SMS and WhatsApp verification with guest WiFi access in one flow. The verified phone number is matched to the session records, and access logs are time-stamped and stored centrally — covering local compliance requirements (such as Türkiye's Law 5651) without any manual work.
