Whenever idiotic passwords are discussed, the following story always comes up: five years ago, a group of Slovak hackers breached Slovakia's National Security Bureau (abbreviated NBU), which stores tons of classified information. It was an easy hack. The NBU's master login/password was simply nbusr/nbusr123. After cracking it, the hackers publicized the information, much to the NBU's embarrassment.

What's even worse? Days later, the password was still "nbu123."

That was five years ago, but bad passwords still abound. SplashData, a password management app maker, compiled a list of the 25 worst passwords of 2011, based on millions of stolen passwords that were dumped online. Typically after hackers compromise a server, like Sony's or CIA.gov's, they post all these personal details online.

Many of the passwords are sequential numbers like "12345" or "654321," while others contained messages like "letmein" and "trustno1". Even if you thought you were being clever with "qazwsx," (look at your keyboard, you'll get it) it's number 23 on the list. "Monkey," "password," and "qwerty" are ALWAYS on these lists. I know I'm preaching to the choir here but, seriously?

Having a tough-to-crack password won't thwart a sophisticated cybercriminal, who can use other methods to breach a server in which passwords are stored. But a solid password will at least deter the lowest common denominator like a nosy partner or a low-level hacker using a dictionary attack that simply tries thousands of passwords.

If you, like me, are rather scatterbrained, perhaps it's time to invest in a password management app which generates unique passwords for you and stores them under one password-protected program. LastPass 1.72 Premium is PCMag's Editors' Choice for password managers. It keeps your encrypted password collection online and works across Windows, Mac, and Linux machines.

A few months ago a software architect at Microsoft, compiled after the Sony PSN hack, revealed that most of us have three, easy-to-crack passwords.
