Wi-Fi QR Code Generator
Type your network name and password, print the code, and guests join your Wi-Fi by pointing their camera at it. The code is made on this page, so your password never leaves your device.
What should the code do?
The password is turned into a QR code right here in your browser. It is never uploaded, which matters: many QR sites send it to their server.

Higher levels add spare modules so a scanner can recover a damaged or covered centre.
What is inside the code
How it works
Enter the network name (SSID) exactly as it appears in your phone's Wi-Fi list, including capitals and spaces, then the password. Choose WPA / WPA2 / WPA3 for almost any router made in the last fifteen years, WEP only for very old kit, or None for an open network. Tick Hidden network if your router does not broadcast its name.
The code holds a short text in the standard Wi-Fi format, for example WIFI:T:WPA;S:Cafe Guest;P:latte2026;;. Special characters such as ; , : \ " in the name or password are escaped with a backslash for you; forgetting that is the most common reason a home-made Wi-Fi QR code fails. Open What is inside the code to see the exact text.
On an iPhone, open the Camera app and tap the Join network banner. On Android, use the Camera or the QR scanner in Quick Settings; Android can also show a QR for a network you are already on (Settings, Wi-Fi, tap the network, Share). Nothing is installed and the password is not shown to the guest unless their phone chooses to display it.
Your password is turned into a code entirely by JavaScript on this page; nothing is sent to a server, logged or stored. Many QR sites upload what you type. For a guest network, consider a separate guest SSID so the code never unlocks your main devices.

Questions
Is it safe to make a Wi-Fi QR code online?
On this page, yes: the code is generated in your browser and the password is never uploaded. Anyone who can photograph the printed code can join the network, so print it for places where you would happily tell people the password.
Why does my Wi-Fi QR code not connect?
Usually the network name does not match exactly (capitals, spaces, a trailing space), the security type is wrong, or a special character was not escaped. Also check the phone is in range of that band.
Does it work with WPA3?
Yes. Choose WPA / WPA2 / WPA3; phones negotiate the exact version with the router. The format has no separate WPA3 value that all phones understand.
Can guests see my password?
The password is inside the code, so a QR reader app can display it. Treat the printed code like the password itself, and prefer a guest network.
What happens if I change my Wi-Fi password?
The old code stops working. Make a new one; nothing here expires or needs renewing otherwise.
Does the hidden network option matter?
Only if your router hides its name. It adds H:true so phones know to look for a network that is not broadcasting.
