Wi-Fi QR Codes — Share Your Network Without Sharing Your Password

How a Wi-Fi QR code works

When someone scans a Wi-Fi QR code with their phone, a prompt appears asking if they want to join the network. They tap yes — and they are connected. No typing required. The QR code contains your network name (SSID) and password, encoded in a format that phones understand natively. The phone reads those values and handles the connection automatically. iOS 11 and later and Android 10 and later both support this natively in the built-in camera app.

What information goes into a Wi-Fi QR code

Three pieces of information: network name (SSID), password, and security type (WPA/WPA2 is standard for most home and business networks). All of this is available in your router's settings or on the label on the back of your router. If you have a guest network — a separate network with limited access — use those credentials instead of your main network. This way guests connect to a network that cannot reach your other devices or shared files.

How to create a Wi-Fi QR code

Select the Wi-Fi tab on Universal QR Generator. Enter your network name, password, and select the security type. The QR code appears instantly in the preview. Download as PNG for printing on a card or sticker. Download as SVG if you need a larger or higher-quality version for printing. The password is encoded directly into the QR code pattern. Nothing is sent to any server — the generator works entirely in your browser.

Where to display your Wi-Fi QR code

Frame it and hang it on the wall near the front of your space. Print it on a laminated card for a table, counter or reception desk. Include it in a welcome pack or Airbnb host guide. Add it to a chalkboard or menu board. A simple printed card at A6 or A5 size looks clean and professional. Lamination protects the card from moisture and wear.

Security and privacy considerations

The Wi-Fi password is encoded inside the QR code image. Anyone who has the image can extract the password using a QR reader. This is the same as writing the password on a piece of paper — it is visible to whoever has it. For guests who need temporary access, use a guest network with a separate password you can change afterwards. For the main network, consider whether everyone who scans the code should have long-term access. The QR code itself is static and never expires, so if you change your Wi-Fi password, you need to generate a new QR code.
