How to make a Wi-Fi QR code
A Wi-Fi QR code can save guests from typing network details. Here’s how to create one and share it thoughtfully.
What the code contains
A Wi-Fi QR code stores the network name (SSID), security type, and—on a protected network—the password. A compatible phone can read those fields and offer to join the network.
The code is static: anyone who can scan or photograph it can read and use the network credentials. It is not an expiring guest pass and it does not hide the password from scanners.
Create and check it
Choose Wi-Fi in the Prism generator, enter the network name exactly as configured, select the matching security type, and enter the password. Use Open network only when the network truly has no password.
Generate the preview and test it with a second device before printing. If you rotate the password later, make a new code and remove old copies. A separate guest network is a sensible choice for signs in shared spaces.
Share it only where appropriate
Put the code somewhere guests can reach, but avoid posting it publicly if you do not want unknown visitors to connect. Keep sufficient clear margin around the symbol and use dark modules on a light background for reliable scanning.
