Your password stays on your device
The code is generated entirely in your browser. The network name and password are never sent to QRNever, which matters because a Wi-Fi code is effectively a written copy of your password. You can disconnect from the internet after the page loads and the generator still works.
What the code contains
Wi-Fi QR codes use a small, widely supported text format: WIFI:T:WPA;S:YourNetwork;P:YourPassword;;. iOS 11 and later and Android 10 and later read it natively from the camera app. Special characters such as semicolons, colons and commas in your network name or password are escaped automatically, which is a common reason homemade codes fail.
- WPA / WPA2 / WPA3: choose this for almost every modern router.
- WEP: only for very old equipment.
- None: open networks such as a public hotspot with a captive portal.
- Hidden network: tick this if your router doesn't broadcast its name.
Where people use them
Cafes print them on table tents, Airbnb hosts frame them next to the house manual, offices put them in meeting rooms and event organisers add them to badges. If you change your password, you will need to print a new code, because the password is stored in the code itself. For that reason it's worth keeping a high-resolution copy so reprinting takes a minute.
