2. Clues to your passwords
Another important part of protecting your security online is avoiding posting information that might hint at the passwords you use or the security questions some services have had you answer. (If you’re still using insecure passwords, do yourself a favor and set up a password manager.) Avoid unnecessary posts about your childhood pets, the town where you grew up, or the name of your first girlfriend or boyfriend — all pieces of information that a hacker could leverage against you and that your social network really doesn’t need to know.
