Wi-Fi QR Code Generator
A Wi-Fi QR code holds your network name, password and security type. Scanning it joins the network directly — nobody has to read a password off a wall or type a long string of characters into a phone keyboard.

When to use a wi-fi QR code
- Cafés and restaurants putting guest Wi-Fi on the table card instead of repeating the password all day
- Holiday lets and hotel rooms, where guests arrive at odd hours with nobody at reception
- Offices onboarding visitors onto a guest network without involving IT
- Homes, so guests stop asking — a printed card by the door handles it
Before you print
Use your guest network, not your main one
Anyone who photographs the code has your password permanently. On a guest network that only costs you bandwidth. On your main network it exposes everything else connected to it.
Get the security type right
Picking WPA when the network is open, or the reverse, produces a code that fails silently — the phone tries to connect and gives up with no useful error. Most modern networks are WPA/WPA2.
Hidden networks need the flag set
If your SSID is not broadcast, the code must say so, or scanning finds nothing to join.
Common questions
Does a Wi-Fi QR code work on both iPhone and Android?
Yes. iOS has supported Wi-Fi QR codes in the camera app since iOS 11, and Android since version 10. Both join the network directly from the standard camera — no separate scanning app is needed.
Can someone see my Wi-Fi password from the QR code?
Yes. The password is stored in the code itself, so anyone who scans or photographs it can read it with a decoder. Use a guest network for any code you display publicly.
Do I need to reprint the code if I change my password?
Yes. A Wi-Fi QR code is static — the password is encoded in the image. Changing the password means generating and printing a new code.
