iOS share password functionality has really simplified things for guests. This is a neat idea for an AirBNB or similar short term rentals.

This is probably safe, but I really can't bring myself to do it.

This is a nice idea! I once whipped up a shell script to do the same thing.

UX feedback - disable autocorrections on the input fields [1], you may want to trim white space as well.

On ios it works fine with the default camera app, but what about android? I'd guess support varies depending on vendor?

Running it on Firefox with web inspector opened, I saw no network traffic at all after the page loaded, so it wasn't sending the network name or password anywhere off my device.

Are there any tools to run an untrusted client side web application isolated from the internet?

This method picks up "most" requests, but not all. eg. websocket and webrtc can be used to exfiltrate data but it won't show up on inspector.
