How it works
The code holds three things: your network name, the security type and the password. A phone camera reads it and offers to join the network.
Make one in three steps
- Type your network name exactly as it appears on a phone, including capital letters.
- Choose the security type and enter the password.
- Download the code and print it.
Which phones can scan it
iPhones can scan it with the Camera app on iOS 11 and later. Many Android phones can scan it with the camera app too, and others use Google Lens.
Keep it safe
The password sits in the code as plain text, so anyone who can scan or photograph the code can read it. That is fine for a guest network, which is a separate network for visitors that doesn't give access to your own devices. Most routers can set one up. Don't put a code for your main network where everyone can photograph it.
If you change the password
Old codes stop working, and a Wi-Fi code can't be edited after it is printed. Keep the guest password stable, or plan to reprint.
Printing and placing it
Put the code on a table card, a counter stand or by the entrance. Use dark code on a light background, and avoid glossy paper that creates glare. Laminate it so it lasts. Our size guide shows how big to print it, and the tool's check will warn you if the code is too dense or low-contrast.
Special characters and hidden networks
Names and passwords with symbols such as semicolons, commas, colons and backslashes need special handling inside the code. The tool does that for you. If your network is hidden, tick the hidden network box.
Frequently asked questions
How does a Wi-Fi QR code work?
It stores your network name, security type and password in a pattern. When a phone scans it, the phone offers to join that network.
Do Wi-Fi QR codes work on iPhone and Android?
They work on iPhones with the Camera app on iOS 11 and later. On Android, most recent phones can scan them, with Google Lens as an option on others.
Does the QR code contain my real password?
Yes. It is stored as plain text inside the pattern. That is why a guest network is the sensible choice.
Is it safe to put my Wi-Fi password in a QR code?
It is as safe as handing out the password itself. Anyone with the code has the password, so use a guest network and change the password if you need to.
What security type should I choose?
Choose WPA if you are unsure, since it covers WPA2 on nearly all home and office networks. Choose None only if your network has no password. Choose WEP only for very old equipment.
Can I make a code for a hidden network?
Yes. Tick the hidden network box.
Why won't my Wi-Fi QR code connect?
Check the network name (capitals matter), the password and the security type. Then check the code is large enough, high-contrast and free of glare.
What happens if I change my Wi-Fi password?
The old code stops working and you need to make and print a new one.
