Share WiFi without sharing the password aloud
A WiFi QR code encodes everything a phone needs to join your network — name, password and security type. Guests point their camera at it and tap connect; no one dictates a long password or types it wrong. It is ideal for a café, an office guest network, or a card on the fridge at home.
Built on your device
The password is encoded locally and never uploaded, so generating the code is as private as writing the password down yourself. Anyone who can see the printed QR can join — so place it where you would happily show the password, and no further.
