How a Wi-Fi QR code works
The code contains the network name, security type and password in a standard WIFI: format. When scanned, the phone offers to join the network automatically.
Your password is only used inside your browser to build the code. It is never sent to us or stored anywhere.
Which security type should I pick?
Almost every home and business router today uses WPA2 or WPA3 — choose “WPA / WPA2 / WPA3”. WEP is obsolete and only kept for very old equipment. Pick “None” for open networks such as a public café hotspot without a password.
Tick “Hidden network” only if your router does not broadcast the SSID; otherwise leave it off.
How to make a Wi-Fi QR code
- Type your network name exactly as it appears on your devices.
- Choose the security type and enter the password.
- Scan the preview with your own phone to confirm it connects.
- Download and print it — a 5 cm code on the counter works well.

Frequently asked questions
Is it safe to put my Wi-Fi password in a QR code?
Anyone who scans the code can read the password, so treat the printout like the password itself. The generator never uploads it.
The code scans but the phone doesn't connect.
Double-check the SSID spelling and the security type. On some phones, tap the notification after scanning to confirm joining.
