You could always write code that saves the data temporarily until the user reconnects to the internet or even visits the website again. I'm not certain how I would use people's wifi passwords without being at their home, but I'm certain somebody on Hacker News could tell me exactly why it is a bad idea to share your wifi password to the internet.

Doesn't Google track router SSID names and MAC addresses? This definitely used to be a searchable database that was connected to Maps. I can't find any of the old websites but it looks like it might still be accessible via API.

Not a hacker but I'm going to give a easy but not critical example. If you have access to another device in range (say, because you run a botnet) you can jump into another neighboring network. I'm sure someone on HN could give us a much more worrisome example.

Well, if you connected to my service I can probably geolocate you. Or I can use a SSID=>lat/lon database to find where your wifi is assuming you have a unique name for your Wi-Fi network. Then I can go there and connect a laptop it and do nefarious stuff from there, and attribute it to you. Threaten the president, torrent Linux ISOs, etc.

Surely Linux isos are among the least nefarious things to torrent ha

Use private browsing?

Yes you're right, that would probably prevent it
