WiFi QR Code Generator: Let Guests Connect Without Typing the Password
One scan and guests are on your network. No app required. Here's how it works and how to make one that looks good on your counter card.
If you run a café, hotel, co-working space, or Airbnb, you've had this conversation a hundred times: guest asks for WiFi, you recite a 16-character password, they mishear it, type it wrong, ask again. A WiFi QR code eliminates that entirely. One scan from the camera app and the phone joins the network automatically — no app, no typing.
How WiFi QR codes actually work
A WiFi QR code encodes a plain-text string in a special format the operating system recognizes. It looks like this:
WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;
The fields are:
T— security type:WPAfor WPA/WPA2/WPA3,WEPfor older WEP, ornopassfor open networksS— SSID (your network name, exactly as it appears in WiFi settings)P— password (omit for open networks)
You don't need to write this yourself. customqr.codes has a dedicated WiFi QR mode: enter your network name and password, choose your security type, and the format is handled for you.
Device support — no app needed
This is the part that surprises most people. You don't need a special QR scanner or any third-party app:
- iPhone/iPad (iOS 11+): Open the stock Camera app, point it at the QR code, tap the “Join Network” banner that appears.
- Android (10+): The stock Camera app handles it natively. On Android 9 and earlier, you may need the Google Lens app, but virtually no guest devices are that old in 2026.
Coverage at this point is effectively universal. You can put a WiFi QR code on your counter and confidently tell guests “just scan that.”
Security considerations
The password is encoded in the QR code, so anyone who scans it can read it if they have a raw QR decoder. For most businesses this is a non-issue — your guest WiFi password isn't a crown jewel. If it concerns you:
- Use a dedicated guest WiFi network, separate from your business network.
- Rotate the password periodically and reprint the card. Because the QR code is a static file, reprinting takes about 30 seconds.
- Don't print the password in plain text on the same card as the QR — the QR is the credential, not a label for the password.

What to print it on
The placement depends on your venue type:
Cafés and restaurants
A small table tent or laminated A6 card works well. Put it next to the condiments or on the bar. Include the network name as text too — some guests just want to confirm they're connecting to the right network.
Hotels and serviced apartments
A card in the welcome folder or mounted on the desk near the TV. Consider two QR codes side by side if you have separate 2.4GHz and 5GHz networks — label each clearly.
Airbnb and short-term rentals
Print a card and frame it — something that looks like it belongs rather than a sticky note. Guests see it immediately when they arrive, which reduces the “what's the WiFi?” message before they've even unpacked. Pair it with a checkout instructions card (see our guide on QR codes for Airbnb).
Co-working spaces and offices
Mount it near the entrance or reception desk. If your network changes quarterly, design the card to be reprinted cheaply — a simple design in a standard frame is better than something that needs to be replaced entirely.
Why not just use a dynamic URL QR?
Some people encode a URL that redirects to a page showing the WiFi password. That works, but it requires an internet connection to display — which is circular when the guest doesn't have WiFi yet. The WIFI: format works completely offline. No server, no redirect, no monthly fee.
