How to Create a WiFi QR Code for Your Guests
August 16, 2026
If you've ever read your WiFi password out loud one character at a time — "capital B, lowercase 7, is that a zero or an O?" — a WiFi QR code will change your life. Guests point their camera at the code, tap a prompt, and they're connected. No typing, no spelling, no shared password written on a sticky note.
This guide shows you exactly how to create one for free, and where it's most useful.
How a WiFi QR code works
A WiFi QR code stores three pieces of information: your network name (SSID), your password, and the security type (almost always WPA/WPA2 on modern networks). When someone scans it, their phone reads those details and offers to join the network automatically.
It's a static QR code, which means it's free, never expires, and works forever — as long as your network name and password stay the same. (If you change your WiFi password, you'll need to make a new code.)
Importantly, the code is generated in your browser — your password is never uploaded to or stored on any server when you use a privacy-respecting tool like QR Code Generator (QRGen).
Step 1: Gather your WiFi details
You'll need:
- Network name (SSID): the exact name of your WiFi network, spelled correctly and matching capitalization.
- Password: your WiFi password, again exactly as it's set.
- Security type: WPA/WPA2 for almost all modern networks. Choose "WEP" only for very old equipment, or "None" for an open network with no password.
A tip: get these exactly right. A WiFi QR code with a single wrong character in the password will fail silently — the phone will try to connect and simply won't.
Step 2: Open the WiFi QR code generator
Go to the WiFi QR Code Generator at QR Code Generator (QRGen). You'll see fields for the network name, password, and security type.
Step 3: Enter your network details
- Type your network name exactly as it appears.
- Enter your password.
- Select your security type (WPA/WPA2 for most people).
- If your network is hidden, tick the "hidden network" option.
The QR code preview updates instantly as you type.
Step 4: Customize (optional)
You can style the code to match your space — change the colors, round the modules, or add a small logo in the center. If you add a logo, keep the error correction level at Medium or higher so the code still scans reliably.
For a code you'll print and display, keep strong contrast: a dark code on a light background scans best.
Step 5: Download and display
Download the code as a PNG for quick use, or an SVG if you want it razor-sharp for printing at any size. Then put it where guests will see it:
- Cafes and restaurants: a small tent card on each table.
- Homes: framed in the guest room or by the front door.
- Offices and waiting rooms: on reception signage or a wall poster.
- Airbnbs and rentals: in your welcome book or on the fridge.
Tips for a WiFi code that always works
- Test it first. Before printing a batch, scan the code with both an iPhone and an Android phone to confirm it connects.
- Print it large enough. At least 2 x 2 cm, bigger for wall signage.
- Keep contrast strong. Dark code, light background.
- Reprint if you change the password. The code encodes your current password; a new password means a new code.
Is it safe to share your WiFi as a QR code?
For a guest or customer network, yes — a WiFi QR code is just a convenient way to share credentials you were going to share anyway. The code itself doesn't "phone home" or collect data; it simply hands your phone the login details.
That said, anyone who can photograph the code can join your network, so treat a printed WiFi code the same way you'd treat a written-down password: fine for a guest network, and worth keeping off the public street for your private home network. Many businesses set up a separate guest network specifically for this purpose.
The bottom line
A WiFi QR code turns "what's the password?" into a single scan. It's free, permanent, and takes under a minute to make — enter your network name and password, customize if you like, and download a print-ready code.
