WiFi QR code generator: how it works
Enter your network name and password, print the QR code and put it at your counter, waiting room or guest room. Phone cameras on Android and iPhone recognise WiFi QR codes and connect in one tap. The password stays on your device; nothing is uploaded.
Will the QR stop working if I change the password?
Yes. The password is stored inside the QR code, so make a new one after changing it.
Is it safe to display a WiFi QR code?
Anyone who scans it can join, so only display it where you want guests to connect. Use a separate guest network if your router has one.
How to make a QR code
- Choose what the QR should do: open a link, show text, join Wi-Fi, or save a contact.
- Fill in the details and press Create QR code.
- Scan it with your phone camera to test, then download it for printing or sharing.
Questions
Do these QR codes expire?
No. The information is stored inside the QR code itself, not on a server. It works forever, with no tracking and no subscription.
Can I use my own colours?
Yes, but keep the QR dark on a light background with strong contrast, or phones may fail to scan it. Always test before printing.
Is my Wi-Fi password sent anywhere?
No. The QR is created in your browser. Anyone who scans the printed QR can join your network, so only display it where you want guests to connect.
