How to use a Wi-Fi QR code
- Type the network name (SSID) exactly, including upper and lower case.
- Enter the password and pick the security type. Most routers today use WPA, WPA2 or WPA3.
- Press "Print Wi-Fi card" to print a card with the code, the network name and the password.
Which phones can read it?
iPhones read Wi-Fi codes with the built-in Camera app since iOS 11. Most Android phones read them with the camera or with the QR button on the Wi-Fi settings screen. The code holds a standard string in the form WIFI:T:WPA;S:network;P:password;;.
If you change the password, make a new code. A separate guest network lets you keep the code for longer and keeps your main network safer.
