Using public Wi-Fi

Show description|Hide description

A list of wireless networks, highlighting the options that don’t display a padlock to tell users that they are public networks.

A hotspot is an area where Wi-Fi access is available. This may be through a home network or a public network in places such as restaurants or airports.

Wi-Fi hotspots in coffee shops, libraries, airports, universities and other public places are convenient, but often they’re not secure. If you connect to a Wi-Fi network and send information through websites or mobile apps, there is a possibility it might be accessed by someone else.

To protect your information when using wireless hotspots, send information only to sites that are fully encrypted. Look for ‘https://’ at the start of the web address. The ‘s’ stands for secure. Many browsers also display a padlock symbol when you are on a secure website (see Lesson 4 [Tip: hold Ctrl and click a link to open it in a new tab. (Hide tip)] ). Make sure the site is secure for your entire visit. If you find yourself on an unencrypted page, log out right away. Don’t use mobile apps that require personal or financial information.
