Wi-Fi Password Exporter

On Android at least, you can go to Settings > Network and Internet > Internet > Saved networks to see a list of all Wi-Fi networks you've connected to. I don't know if Wi-Fi passwords get backed up anywhere, so just in case, this allows you to somewhat easily (though still painstakingly) export each Wi-Fi network's password.

  1. Click "Start scanning."
  2. Go to Settings > Network and Internet > Internet > Saved networks.
  3. Tap each network.
  4. Click on the "Share" button.
  5. Scan your fingerprint.
  6. Show the QR code to the webcam until you hear a ding.
  7. Repeat with all the networks.

The networks are saved locally, so you won't lose them if you accidentally close the browser. Once you're done, click the "Download as CSV" button and be happy.
