How to Create a WiFi QR Code (So Guests Scan to Connect)
A WiFi QR code holds your network name, password, and security type in a single scannable square. Guests point their phone camera at it and join instantly, with no reading the password out loud or typing a long string of characters. It is one of the most useful QR codes for cafes, rentals, offices, and homes.
How a WiFi QR code works
The code encodes a short text string in a standard format that phones recognise: your network name (SSID), the password, and the security type (usually WPA/WPA2). When a phone camera reads it, the operating system offers a one-tap option to join that network - no app required on modern iOS and Android.
How to create one
- Enter your network name (SSID) exactly as it appears, including capitalisation.
- Choose the security type - WPA/WPA2 for almost all modern networks.
- Enter the WiFi password.
- Generate the code and download it as an image.
- Print it or display it where guests will see it.
Where to put it
Common spots: a small sign on the counter or table in a cafe, a framed card in a holiday rental or Airbnb, a sticker in a meeting room, or the fridge at home. Anywhere a guest naturally looks when they sit down. Laminating it keeps it clean in busy places.
Hidden networks
If your network does not broadcast its name (a hidden SSID), the QR code needs to flag that, or phones may fail to find the network after scanning. Most generators have a hidden-network option - enable it only if your router is genuinely set to hidden, otherwise leave it off.
Is it safe to share a WiFi QR code?
A WiFi QR code contains your password in plain form, so treat it like the password itself: fine to display to people you would give the password to anyway (guests, customers), but do not post it publicly online where anyone could scan it from a photo. For businesses, a separate guest network keeps visitors off your main network entirely - the safest setup.
Use the WiFi QR Code Generator
The WiFi QR Code Generator builds the code entirely in your browser - your network name and password are never sent to a server. Enter your details, download the image, and print it. Because nothing is uploaded, it is safe to use even for your home or business network.
Frequently asked questions
Do guests need an app to scan it?
No. Modern iPhone and Android cameras read WiFi QR codes natively - guests just open the camera, point it at the code, and tap the prompt to join. Very old phones may need a free QR scanner app.
What if I change my WiFi password?
The old code stops working, because it contains the old password. Generate a fresh code with the new password and reprint it. This is also why you should regenerate the code if you rotate your password for security.
