Wi-Fi QR code generator

What is a Wi-Fi QR code?

The pattern carries three facts: the network name (SSID), the password and the encryption type. Phones are built to read this — both iPhones and Android devices recognize the format natively and offer to join on the spot.

Because it is static, the data lives inside the code. There is no service to renew, no account that lapses, and no dashboard where a hotel chain could change where it points.

How to make one

1. Open the QR builder and pick the Wi-Fi type.
2. Enter the network name exactly as your router shows it, the password, and the security type (most modern networks are WPA/WPA2 or WPA3).
3. Pick a network band or leave it as-is — for most setups the default encoding works on both 2.4 and 5 GHz.
4. Style it to match your interior or menu brand and export PNG or SVG.

Where a Wi-Fi QR earns its keep

Cafés and restaurants place it on menus and table tents. Hotels and B&Bs frame it by reception and in every room. Home households put it on the fridge for visitors. At events, the code goes on the stage banner or badge insert.

One rule of thumb wherever it goes: the sign should be readable from where guests sit, and the QR itself at least 2 cm wide.

What to avoid

Do not encode your main network password on a public counter — anyone in the room can decode it. Generate a guest network with its own password and print that.

If you rotate guest passwords for security, remember the printed code can never change: either accept a reprint now and then, or pair the printed code with a guest network whose password is long-lived.
