How to Make a Wi‑Fi QR Code (Free) for Your Home, Café or Office
Create a Wi‑Fi QR code guests can scan to join your network with no typing. Static vs dynamic Wi‑Fi codes, where to place it, security tips, and troubleshooting.
A Wi‑Fi QR code lets guests join your network by pointing their camera at it, with no password to read out, mistype, or write on a chalkboard. iPhones (iOS 11+) and Android phones (Android 10+) support it natively. This guide shows how to make one in under a minute, where to put it, and when you should use a static or a dynamic version.
How a Wi‑Fi QR code works
The code contains a small text record: network name (SSID), security type (WPA/WPA2/WPA3, WEP, or open) and the password. The phone's camera recognises the format and offers a "Join network" prompt. Nothing is sent anywhere; the join happens entirely on the phone, so it works even with no internet yet.
Make a Wi‑Fi QR code (free, no account)
- Open the QR Walrus generator and choose Wi‑Fi.
- Enter the network name exactly as it appears on your router, case included.
- Pick the security type (almost always WPA/WPA2) and type the password.
- Optionally add your logo and colours.
- Download SVG or PNG and print.
Static Wi‑Fi codes are free forever and need no sign-up. The password is stored inside the code itself.
Static vs dynamic Wi‑Fi QR code
| Static (recommended for most) | Dynamic | |
|---|---|---|
| Joins the network automatically | Yes, from the camera prompt | Opens a page showing the network details to copy |
| Needs internet to scan | No | Yes (to load the page) |
| Change the password later | Reprint the code | Edit in the dashboard, no reprint |
| Count how often it is used | No | Yes |
| Where the password lives | Inside the printed code | On the QR Walrus page behind the code |
Use static for homes, Airbnbs and small cafés: it just works. Use dynamic when you rotate the password regularly (offices, coworking, hotels) and do not want to reprint signs each time; guests will already have mobile data to load the page.
Where to put it
- A table tent or counter card in a café, next to the menu code.
- The welcome card or fridge in a holiday rental.
- The reception desk and meeting rooms in an office.
- Hotel rooms, printed on the TV info card.
- Your home: a small framed print for visitors.
Label it "Scan to join Wi‑Fi" and keep the network name printed next to it for people with older phones.
Troubleshooting
- No prompt appears: the phone may be too old, or the camera app has QR scanning turned off in settings. Google Lens or any QR app will still read it.
- "Cannot join": check the SSID spelling and capitalisation, and the security type (WPA2 vs WPA3).
- Hidden networks: supported, but the phone will take a few seconds longer to connect.
- Enterprise (802.1X) networks with usernames are not supported by the Wi‑Fi QR format.

Frequently asked questions
Is a Wi‑Fi QR code safe?
A static Wi‑Fi code contains the password, so anyone who photographs it can read it. Place it where guests are, not in a street-facing window, and use a separate guest network for the public.
Does a Wi‑Fi QR code need internet to work?
A static one does not; the phone joins directly from the camera prompt. A dynamic one opens a page with the details and needs a connection to load it.
Which phones can scan Wi‑Fi QR codes?
iPhones on iOS 11 or later and Android phones on Android 10 or later, using the built-in camera.
