Your Wi‑Fi password stays on your device
Most WiFi QR generators send your network name and password to their server. This one doesn't. The code is made in your browser, so your password is never uploaded or stored anywhere.
Does it work on iPhone and Android?
Yes. iPhones (iOS 11 and later) and modern Android phones can join a network directly from the built-in camera app. On some older Android phones you may need Google Lens or the QR scanner in the quick-settings panel.
Ideas for using your WiFi QR code
- Frame it near the entrance of your café, restaurant, salon or waiting room.
- Add it to your Airbnb or holiday-rental welcome guide.
- Stick it on the fridge so visiting friends and family can connect with one scan.
- Put it on meeting-room tables and event badges for a guest network.
Tip: if you change your Wi‑Fi password, you'll need a new QR code, because the old one still holds the old password.
How it works
The code stores your network details in a short text format that phones recognise: the security type, the network name and the password, for example WIFI:T:WPA;S:Joes Cafe Guest;P:coffee2024;;. When the camera reads it, the phone offers to join that network. Anyone with a QR reader app can see the password inside, so treat the printed code like the password itself.
Use a guest network
Most routers can run a separate guest network. Guests get internet access but can’t see your computers, printers or smart devices. It is the right network to put in a printed code, and you can change its password without disturbing your own devices.
Printing and placing it
- Add the network name and a line like “Scan to join the Wi‑Fi” next to the code.
- For a table card or fridge magnet, 3 to 4 cm wide is plenty.
- When you change the password, make a new code and replace every printed copy.
