How does a WiFi QR code work?

A WiFi QR code encodes your network credentials in the WIFI: format that smartphones recognize. When scanned, the device automatically connects to your network without the user typing the password.

Is my WiFi password safe?

Your QR code is generated entirely in your browser — your password never leaves your device or gets sent to any server. The password is encoded into the QR image itself.

Which devices can scan WiFi QR codes?

iOS 11+ and Android 10+ can scan WiFi QR codes natively using the camera app. Older devices may need a dedicated QR code scanner app.

Can I share a hidden network?

Yes! Check the "Hidden network" checkbox when generating your QR code. The QR will include the H:true flag so devices know to connect even though the network doesn't broadcast its SSID.

Do WiFi QR codes expire?

No. The QR code itself never expires. However, if you change your WiFi password, the QR code will no longer work and you'll need to generate a new one with the updated credentials.
