BEING SAFE on PUBLIC WI-FI

Public Wi-Fi is always dangerous, whether a password is required or not.

AVOIDING

INTERNET PROTECTION

LAN SIDE PROTECTION

On a public network is it very likely that all the other users on the local network can see and try to contact your device. You need just as much protection on the LAN side, as you do on the WAN/Internet side.

SSIDs AND PRIVACY

Wi-Fi devices generally keep a record of the networks/SSIDs they have connected to. This makes it easy or automatic to re-connect to known networks. Fine. Except, when they broadcast this list, it exposes the places you have visited to anyone able to record this broadcast. It may also expose where you live or work.

For some additional privacy, periodically review the list of saved SSIDs and delete the ones you do not expect to use in the future (or the ones you do not want anyone to know about).
iOS version 17: Settings -> Wifi -> Edit (link in the top right corner)
Windows: coming ....
Android 14 (on a Pixel phone): Settings -> Network and Internet -> Internet -> Saved Networks. Click on an SSID you want to delete, then Forget.
macOS: coming....
