Your browser makes the code — nothing is sent anywhere.
The iPhone camera and most Android phones read this code without any app: the phone offers to connect.
The password is never sent anywhere — your browser builds the code. But anyone who scans it can connect, so a separate guest network is best.
The old code will stop connecting. Make a new one with the new password — it takes a minute.
