Sign-in method · Self-provision via SMS

The phone
is the identity.

Visitors enter their phone number and verify with a one-time code. Same identity-bound, audit-friendly model as email self-provision — designed for venues where phones are the de-facto digital identity.

One field. Six digits. Identity verified — and a phone number you can talk to.

What's broken today

Email is hard on a phone

Asking a tired traveler at a quick-service counter to type their corporate email on a 5-inch screen is a recipe for typos, drop-off, and a worse experience than open Wi-Fi.

Email entry on mobile is awful

Auto-correct mangles addresses. Drop-off rates climb. Half your potential identities never finish onboarding.

Anonymous sessions for everyone else

If they don't want to type the email, they fall back to your open SSID — and you learn nothing about them.

No phone-based audit trail

Many regions require a verifiable identity for public Wi-Fi. A phone number works where email doesn't.

SMS marketing channel never opens

Without consent collection, you have no way to reach this audience for offers, alerts, or surveys.

The sign-in flow

Three taps. Verified identity.

01

Visitor enters phone number

One field on a branded captive portal. Country code prefilled by IP geolocation.

02

SMS code arrives

One-time code via SMS within seconds. Resend if it gets lost.

03

Verified, on the network

Type the code. Land on your configured redirect. Session bound to the verified phone number.

See everything that matters

Phone-verified, audit-ready, marketing-friendly.

Most people can type their phone number faster than their email and never misspell it. SMS verification turns that into a reliable identity bound to a real device.

01

Verified phone per session

Every session has a real phone number behind it. Search by phone, filter by region.

02

Session length per identity

How long they stayed, how often they returned. Repeat-visitor patterns become visible.

03

Devices per phone

Phone, tablet, sometimes laptop too. Quota enforcement is yours to set.

04

Where they connected

Per-site, per-AP attribution. Useful for retail and transport hub analytics.

05

Opt-in lists for SMS

Verified phone numbers with consent — exportable for SMS campaigns and offers.

06

Audit-ready exports

Per-period reports of phone-verified sessions — meet regional compliance for public Wi-Fi.

Where it fits

Anywhere phones beat email entry

01

Retail & quick service

Cafes, fuel stations, retail venues — fast onboarding without keyboard friction.

02

Transport hubs

Stations, ports, airports — phone-verified Wi-Fi where regulations require it.

03

Public city Wi-Fi

Open spaces and downtown cores — verifiable identity for accountable access.

04

Sports & event venues

Phones-out events where SMS is the natural channel — and the marketing surface.
