There’s nothing you can do if hackers get into a database with your password in it, but you can still protect yourself for all the other worst-case scenarios involving hacking. In this video, we go over ways to make your passwords harder to crack.
First, don’t make it easy on hackers by choosing a common password. Splashdata uses security breaches to gather 'most popular passwords' lists each year. The word 'password', number sequences, and other simplistic phrases or numbers fill the top spots. Also, don’t use your name, a password related to another one you might have on a different site, or a login name.
Instead, experts recommend using 15 characters, upper-case letters, better yet nonsensical words with special characters and numbers inside them.
