How to create a Wi-Fi QR code
A Wi-Fi QR code lets guests join a network on compatible phones without typing its name and password. Use it on a welcome card, reception desk, or guest information sheet.
Choose the network
Use a guest network when your router offers one. In the QRLio generator, select Wi-Fi and enter the exact network name (SSID), including spaces and capitalization. Choose the security type that matches your router, enter its password, and mark Hidden network only if the network is actually hidden.
Try a practical example
For a guest network named Cafe Guest, enter Cafe Guest as the SSID, select the matching security setting, and enter its actual password. Add a visible label such as “Scan to join our guest Wi-Fi” beside the printed code; the label does not need to contain the password.
Download and test
Download PNG for a simple welcome card or SVG for a print layout that needs resizing. Scan the code with another phone, accept the connection prompt, and confirm it joins the intended network. Phone support varies, so keep an alternative way for guests to connect.
Treat the code like the password
The Wi-Fi details are encoded in the image and can be read by anyone who has it. Share it only where you would share guest network access. Guest generation keeps your content in your browser, but a downloaded or printed code contains those details. If the network name or password changes, generate and replace the static QR code.
