How a Wi-Fi QR code works

The code stores your network details in a short, widely supported format: WIFI:T:WPA;S:CafeGuest;P:sunny-day-42;;. T is the security type (WPA, WEP or nopass for an open network), S is the network name and P the password. For a hidden network, H:true; is added. Characters that have a special meaning in this format, such as a semicolon, colon, comma, quote or backslash, are escaped with a backslash, so passwords containing them still work.

On iPhone (iOS 11 and later), pointing the Camera app at the code shows a “Join network” prompt. Most Android phones from Android 10 onward offer the same through the camera, Google Lens or the Wi-Fi settings screen, which has its own QR scan button. The phone connects directly; no app or internet access is needed to read the code.

The WPA option covers WPA, WPA2 and WPA3 networks. Choose WEP only for very old routers.

Where it helps

  • A table tent at a café lets guests connect while they wait for their order, and staff no longer spell out the password at the counter.
  • A vacation rental frames the code next to the front door, so new guests get online even when the host is not reachable.
  • A meeting room shows the guest network code on the wall for visitors who bring their own laptop and phone.
  • At home, a code on the fridge saves you from looking up the router sticker every time friends visit.

Tips before you print

  1. When you change the Wi-Fi password, the printed code stops working. Make a new code and replace the old prints at the same time.
  2. Use a separate guest network if your router has one. Anyone who photographs the code can read the password from it.
  3. Type the network name exactly as it appears, including capital letters and any _5G suffix. Names are case-sensitive.
  4. The Print sheet adds a “Connect to Wi-Fi” headline and the network name, so people who cannot scan can still type it in.

Questions

Does a Wi-Fi QR code work on iPhone?
Yes. Since iOS 11, the built-in Camera app recognizes Wi-Fi codes and shows a prompt to join the network.
Can I change the password later without reprinting?
No. The password is stored inside the code, which is static. After a password change you need to generate and print a new code.
Is my Wi-Fi password stored on your server?
The code is generated in your browser. When you save, copy or print, what you entered may be logged as described in the Privacy Policy, but Wi-Fi passwords are always masked before storage.
Does it work for hidden networks?
Yes. Tick Hidden network and the code tells the phone to look for a network that does not broadcast its name. Support for hidden networks is less consistent on older phones, so test it.
Will it work for a hotel network with a login page?
It connects the phone to the network, but any sign-in page that appears afterward still has to be completed by hand.
