Question 1

How do smartphones connect to Wi-Fi from a QR code?

Accepted Answer

When scanned by the camera app, iOS and Android automatically recognize the standard Wi-Fi configuration format (WIFI:S:...;P:...;;) and show a banner asking "Join this network?".

Question 2

Is my Wi-Fi password sent to any server?

Accepted Answer

Never. PDFly XO runs the Wi-Fi QR encoder completely locally in your browser. We never log, upload, or transmit network credentials.

Question 3

Does this support hidden networks and WPA3?

Accepted Answer

Yes. XO QR supports WPA/WPA2/WPA3, legacy WEP, open networks, and hidden SSID networks.
