FAQ
How does the WiFi QR work?
Fill in SSID/password and guests scan to join automatically — no manual typing needed.
Do generated codes expire?
Never. A QR merely encodes its content, staying valid forever; generation never touches a server.
Is my content uploaded?
No, encoding runs entirely in your browser — even WiFi passwords stay on-device.
