How to create a WiFi QR code (and never spell out your password again)
How many times have you had to spell out your WiFi password to guests? "Capital M, underscore, seven…". There is a much more elegant solution: a WiFi QR code. Anyone who scans it with their phone camera connects to your network automatically, without typing anything.
What you need
- The exact network name (SSID) — the one that appears in your phone's WiFi list.
- The network password.
- The security type: almost all modern networks use WPA/WPA2/WPA3. If you are not sure, keep the default option.
Step by step
- Open our QR code generator and pick the "WiFi network" option.
- Type the network name and password exactly as they are, respecting upper and lower case.
- Click "Generate QR code" and download the PNG image.
- Print it and place it where your guests will see it: the fridge, the entrance, the living room… For businesses it works great next to the till or on each table.
Good to know: the QR code is generated in your browser and your password is never sent to any server, so it is safe even for business networks.
How your guests connect
On iPhone (iOS 11 or later) and Android (10 or later) they just open the camera, point it at the code and tap the "Join network" notification. On Android, Google Lens works too. No app installs required.
Ideas for using it
- Vacation rentals: leave a framed QR code by the door; guests connect on their own and stop messaging you for the password.
- Cafés and restaurants: print the WiFi QR on the same sheet as your menu QR.
- Offices: a QR code for the guest network keeps your internal network private.

Frequently asked questions
Does it still work if I change my WiFi password?
No: the QR code carries the password encoded inside it, so if you change the password you need to generate a new code. It takes a minute and it is free.
Is it safe to display the WiFi QR code openly?
Anyone who scans the code can connect, just as if you had told them the password. Only place it where the people you want to give access can see it, and for businesses use a guest network separate from your main one.
Does it work for open networks with no password?
Yes: choose "Open network" as the security type and leave the password empty. The QR code will connect the user directly.
Can someone read the password inside a WiFi QR code?
Yes — any QR reader that shows the raw content will reveal the password (it travels in plain text inside the code). That is why you should not use it for networks you want to keep truly private.
