How to Make a QR Code for Wi-Fi

What you need

You only need two things: your network name (SSID) and its password. You should also know the security type — almost always WPA/WPA2/WPA3 on modern routers.

Make the code

1. Open the Wi-Fi QR code generator.
2. Type your SSID exactly as it appears (it is case-sensitive) and your password.
3. Leave security on WPA unless you have an open or legacy WEP network.
4. Download the code as PNG for screens, or PDF to print.

Where to put it

Print the code and place it where guests naturally look: a café table tent, a reception desk, the back of a hotel-room door, or a frame in your living room for visitors. When a phone camera scans it, the phone offers to join the network automatically.

Stay safe

• The code contains your real password, so only display it where you trust the audience.
• For public spaces, consider a separate guest network so visitors never touch your main devices.
• If you change your Wi-Fi password, generate a fresh code — the old one will stop working.
