A card on each table beats a password scrawled on a chalkboard, and staff stop being asked.

Step by step
How it works
No manual required — but here's the whole flow, start to finish.
-
Type your network name (SSID) exactly as it appears on the device — it is case-sensitive
-
Enter the password and pick the security type (WPA/WPA2 covers almost every modern router)
-
Tick "hidden network" only if your router does not broadcast its name
-
Download the PNG, print it, and test it with your own phone before it goes on the wall
Under the hood
What the code actually contains
WIFI:T:WPA;S:Cafe Guest;P:flatwhite2026;H:false;;The WIFI: format is a plain-text convention every modern phone camera understands. T is the security type, S the network name, P the password, H whether the network is hidden.
Use cases
Who reaches for this.
Holiday lets and Airbnb
In the welcome pack. Guests are online before they have put the bags down.
Offices and meeting rooms
A guest-network code by the door means visitors connect themselves without involving IT.
Home
On the fridge, so a 20-character password you chose properly stops being a reason to pick a weak one.
FAQ
Questions, answered.
Do people need an app to scan it?
No. The iPhone camera has handled WiFi codes since iOS 11, and Android since version 10. Point the camera, tap the banner that appears, and the phone joins. Very old devices may need a QR app.
Is it safe to put my WiFi password on the wall?
The password is inside the code, so anyone who can photograph the code can extract it. That is fine for a guest network and a bad idea for the network your work laptop is on. Most routers can run a separate guest SSID — use that.
My network name has spaces or a semicolon — will it work?
Yes. Special characters are escaped when the code is built. Type the name exactly as the router shows it, including capitals.
Does my data get uploaded anywhere?
No. The code is drawn in your browser with JavaScript — nothing you type is sent to AroraLabs or to any other server, and nothing is stored. You can prove it: load the tool, go offline, and it still works.
