Wi-Fi QR codes make it easier for visitors to join a wireless network without typing a long password. They are useful at cafés, offices, classrooms, homes and short-stay accommodations. A standard Wi-Fi QR code contains the network details in text that compatible scanner apps recognize.
What details are required?
You need the Wi-Fi network name (SSID), security type and, for protected networks, the password. The name and password are case-sensitive. Most ordinary home networks use WPA-family protection. If the network does not have a password, select the open-network option.
How to create one
- Open the QRBento Wi-Fi QR generator.
- Enter your exact network name and select the security setting.
- Enter the password if the network is protected.
- Generate the QR, then scan with another device to check that the proposed network matches yours.
- Download PNG or SVG for a guest sign.
Privacy: your QR is not a secret vault
A QR code is an encoding format, not password encryption. Anyone who receives the code may be able to decode and copy its contents. A printed Wi-Fi QR is equivalent to sharing the guest password with people who can see it. Consider a separate guest Wi-Fi network that cannot access personal devices, and change credentials when needed.
Why doesn't it connect on some phones?
Common causes include a misspelled SSID, wrong security selection, outdated password, a disabled wireless network, or a camera app that does not interpret Wi-Fi data. If a device only displays the raw encoded text, that scanner may not support automatic Wi-Fi joining.
Tips for a practical sign
Keep the print high contrast and away from decorative artwork. Add a plain-text guest network name below the code as a fallback. Test the printed version from a comfortable standing distance, and avoid placing private home-network credentials in publicly accessible areas.
