Have you ever seen a pop-up asking you to use your Facebook account to login to something? This would save time you may think. Right you are, but think it through. If you do this, the place asking you will gain access to everything you do on Facebook including your friends list. I am sure we all read the fine print when we sign up for something…NOT. Take the time to sign in without linking. The more you link together the more vulnerable your information is.
