The availability of free wifi hotspots has exploded recently with McDonalds and Starbucks both offering free wifi at all of their locations. With most of these public hot spots you don't need a password to log in. Wifi hot spots that don't use passwords don't use any sort of encryption when your data is sent back and forth across the internet. This opens you to the possibility that others can steal your private information.

Locate free wifi hotspots near you

There are a couple of things you can do to protect yourself when you are using an open wifi hotspot:

  • The simplest thing to do is to not send any private personal information over the internet when you are at a public hot spot. By not sending any private data, you don't even need to worry if your browser and the website and taking care to protect your data.
  • If you do access sites such as shopping or banking or anywhere you need a password to login, make sure that the website is using a secure connection. You can tell if the connection is secure by looking at the very beginning of the web address. If it starts https:// rather than http:// (notice the additional "s") you have a secure connection. You will also see a padlock icon at the top right of the Safari window. Many websites will use a secure connection when you log in (sending your password) but then not use a secure connection for sending most of its data. Keep an eye out for that extra "s" or the padlock icon anytime you are sending private personal information across the internet.
Note: Once you have logged into an encrypted wifi hotspot, your Mac will remember the password for the next time you login. While a stored password makes it easier to login, it can make it harder to know if the hotspot is encrypted or not. You can easily tell, however, by clicking on the Airport icon on the right of the Menu Bar. Encrypted hotspots have a padlock next to their name.
