Know the risks you expose yourself to when you connect your device to public Wi-Fi at a coffee shop, restaurant, library, or any other public space. It’s best to stick to official wi-fi networks advertised by the building or place of business. Don’t connect to any networks you don’t recognize: hackers can easily create wi-fi networks and capture private information from users who connect to them.
When you are on a public Wi-Fi network, even if it requires a password, do not conduct sensitive activities while connected. It is ridiculously easy for even amateur hackers to gain access to login information and more of the other users connected on the same Wi-Fi network. Don’t do any online banking or login to other personal accounts you do not want spying hackers to gain access to. Turn off remote sharing of files, folders, printers if you are on a laptop. If possible, only visit HTTPS sites (check for this at the beginning of the site’s URL), as this means the data you are passing back and forth between websites is encrypted. If you must access sensitive information online, consider doing it on your smartphone where you are connected via your cellular network, or wait until you get home.
