How to Create a Wi-Fi QR Code (Free, No Apps to Install)

A Wi-Fi QR code is the easiest way to share your network with guests, customers, or Airbnb visitors. They scan it with their phone camera and connect — no typing a 20-character password.

The Wi-Fi QR code format

Every modern phone camera (iOS 11+ and Android 9+) recognizes this exact string format:

WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;

• T = security type: WPA, WEP, or nopass for open networks
• S = SSID (your network name, case-sensitive)
• P = password (leave empty for open networks)
• End with two semicolons

Step-by-step: make your Wi-Fi QR code

1. Open our QR Code Generator
2. Paste the WIFI: string above with your real SSID and password
3. Pick a size (300px is fine for printing on letter-size paper)
4. Click Download PNG and print or share

Keep your guest network secure

If you're putting the QR code on display, set up a separate guest network on your router and generate a fresh password with our Password Generator. That way the main network credentials never end up on a fridge magnet.
