Question 1

How does a WiFi QR code work?

Accepted Answer

The code contains your network name, encryption type, and password in the standard WIFI: format. When scanned with the camera app on iOS or Android, the phone offers to join the network directly — no typing required.

Question 2

Is the WiFi password visible to anyone who scans the code?

Accepted Answer

Yes. The password is embedded in the QR code as plain text, and any QR reader can display it. Treat the printed or shared image like the password itself and only give it to people you would tell the password to.

Question 3

Which encryption type should I choose?

Accepted Answer

Pick what your router uses. WPA/WPA2 covers WPA, WPA2, and WPA3 personal networks — phones treat them the same when joining. WEP exists only for very old hardware, and None is for open networks without a password.

Question 4

Why might the code fail to scan?

Accepted Answer

Very long passwords make the code denser and harder to read when printed small. Print the code at a reasonable size with good contrast, or raise the error-correction level if the print may get dirty or damaged — redundancy helps, but also increases density.

Question 5

Is my WiFi password uploaded anywhere?

Accepted Answer

No. The QR code is generated entirely inside your browser; your network name and password never leave your device, nothing is uploaded or tracked, and the tool works offline once the page has loaded.
