How to Create a QR Code for Your WiFi Network
Sharing WiFi passwords is awkward. A QR code lets guests connect with one scan — no password typing required. Here's how to set it up.
Every café, hotel, office, and Airbnb deals with the same problem: guests want WiFi, and sharing the password is awkward. A WiFi QR code solves this elegantly — scan once, connected instantly, no password visible or typeable.
How WiFi QR Codes Work
A WiFi QR code encodes a special string format that iOS and Android understand natively:
WIFI:T:WPA;S:YourNetworkName;P:YourPassword;H:false;;
When scanned, the phone offers to join the network automatically. No app required. This format has been supported since iOS 11 and Android 10.
Option 1: Static WiFi QR Code (for permanent installations)
If your WiFi password never changes (or you're okay making a new code when it does), a static QR code is the simplest option:
- Log in to QR Node
- Create a new QR code → select "Static"
- Use the WiFi format string as your content
- Download and print
Option 2: Dynamic Code Pointing to a Page with WiFi Details
For businesses that rotate passwords regularly, a dynamic QR code pointing to a webpage that displays the current WiFi password works better:
- Create a simple webpage (or Notion page) that shows your WiFi name and password
- Create a dynamic QR code pointing to that page
- When you change the password, update the page — not the QR code
- The printed QR code never needs to be replaced
Design Tips for WiFi QR Codes
- Use a clear heading: "Guest WiFi — Scan to Connect"
- Include the network name in text (some phones still ask you to confirm)
- Print at least 5 × 5 cm for table placement
- Laminate for longevity in public spaces
Security Considerations
A WiFi QR code is only as secure as your WiFi network itself. Best practices:
- Use a separate "Guest" network, isolated from your internal devices
- Set bandwidth limits on your guest network
- Rotate the guest password periodically (and update your page if using the dynamic approach)
- Never encode your main network credentials in a publicly displayed QR code
Done right, a WiFi QR code is one of those small touches that makes a meaningful difference to visitor experience. Hotel and Airbnb hosts report it as one of the most appreciated amenities they've added.
