How to make a Wi-Fi QR code

A Wi-Fi QR code stores your network name, password and security type. When someone points an iPhone or Android camera at it, the phone offers to join the network, with no typing. It's ideal for homes, cafés, clinics, offices and rental flats.

Make the code

1. Open the QR code generator and choose Wi-Fi.
2. Type the network name (SSID) exactly as it appears on phones, including capital letters and spaces.
3. Type the password and pick the security type. Most routers use WPA/WPA2/WPA3.
4. Download a PNG for screens or the SVG for printing.

The code is made in your browser, so your Wi-Fi password is never sent anywhere. And because the details are stored in the code itself, it never expires: it works until you change your password.

Which phones can scan it?

iPhones on iOS 11 or later and most Android phones on Android 10 or later read Wi-Fi QR codes straight from the camera app. On older Android phones, use Google Lens or the QR scanner in quick settings.

Printing tips that save you trouble

• Size: at least 3 × 3 cm (about 1.2 inches) for a table card; bigger on a wall where people stand back.
• Contrast: keep the code dark on a light background.
• Test before printing: scan it with an iPhone and an Android phone.
• Add a line of text under the code, such as "Scan to join Wi-Fi", plus the network name for laptops.

A guest network is safer

Anyone who scans the code can read the password. In a shop or office, turn on your router's guest network and put that one in the QR code, so visitors can't reach your printers, cameras or computers.
