    25 Worst Passwords of 2011 [STUDY]

    Pro tip: choosing "password" as your online password is not a good idea. In fact, unless you're hoping to be an easy target for hackers, it's the worst password you can possibly choose.

    "Password" ranks first on password management application provider SplashData's annual list of worst internet passwords, which are ordered by how common they are. ("Passw0rd," with a numeral zero, isn't much smarter, ranking 18th on the list.)

    The list is somewhat predictable: Sequences of adjacent numbers or letters on the keyboard, such as "qwerty" and "123456," and popular names, such as "ashley" and "michael," all are common choices. Other common choices, such as "monkey" and "shadow," are harder to explain.

    As some websites have begun to require passwords to include both numbers and letters, it makes sense varied choices, such as "abc123" and "trustno1," are popular choices.

    SplashData created the rankings based on millions of stolen passwords posted online by hackers. Here is the complete list:

    • 1. password
    • 2. 123456
    • 3.12345678
    • 4. qwerty
    • 5. abc123
    • 6. monkey
    • 7. 1234567
    • 8. letmein
    • 9. trustno1
    • 10. dragon
    • 11. baseball
    • 12. 111111
    • 13. iloveyou
    • 14. master
    • 15. sunshine
    • 16. ashley
    • 17. bailey
    • 18. passw0rd
    • 19. shadow
    • 20. 123123
    • 21. 654321
    • 22. superman
    • 23. qazwsx
    • 24. michael
    • 25. football

    SplashData CEO Morgan Slain urges businesses and consumers using any password on the list to change them immediately.

    "Hackers can easily break into many accounts just by repeatedly trying common passwords," Slain says. "Even though people are encouraged to select secure, strong passwords, many people continue to choose weak, easy-to-guess ones, placing themselves at risk from fraud and identity theft."

    The company provided some tips for choosing secure passwords in a statement:

    • 1. Vary different types of characters in your passwords; include numbers, letters and special characters when possible.
    • 2. Choose passwords of eight characters or more. Separate short words with spaces or underscores.
    • 3. Don't use the same password and username combination for multiple websites. Use an online password manager to keep track of your different accounts.

      If I need a new password, I use an online password generator. Once you get used to a new one, it doesn't take too much to remember it. At the moment I have 3 passwords in use, 2 are 10 symbols long, and the other 8, with random capitalisation and numbers throughout.
    • NASREEN BABAR  •  Avenel, United States  •  5 mths ago

      • Vekou 6 mths ago
        Haha, well in sites where you're free to add a security question when retrieving your password, I always write, "What is my password?"
      • Diego 6 mths ago
        nice

    • John  •  New Haven, United States  •  6 mths ago
      This is why my password is "Tryt0HackMe" ... oh #$%$
    • Timmotaus  •  6 mths ago
      Ahh...the power of the media! The information in this article does help to prevent people from getting victimised by hackers, but I'm sure it also informs aspiring hackers of common passwords that they otherwise wouldn't have ever known to be common. This is good (and bad) info for both sides..... So, everyone change your lame passwords, or else there will continue to be more and more disgusting porn on FaceBook, and comprimised accounts. I for one, am sick of it, and I'm sure most of you are as well.
    • Kranky Kat  •  5 mths ago
      Pull a $100 bill out of your wallet. Use the bill's serial number as your password.
      If you don't happen to have a $100, any denomination will do... $25, $7, $3...etc
      Not to overstate the obvious, but... If you can't remember the number, don't spend the bill.
    • Ebony  •  Fresno, United States  •  6 mths ago
      They need to add another one: "computer," that was my friend's password and he got hacked (obviously).
    • Kranky Kat  •  6 mths ago
      My old prison number
    • Erik  •  Denver, United States  •  6 mths ago
      This article teaches outdated password strength information. Brute force algorithms will figure out your password regardless of numbers and special characters if it isn't long enough. An 8-character password like hIth3re! would be cracked inside 2 months using a normal desktop PC (take away one character and it's down to 3 hours), and that number is rapidly going down as computers get faster and faster. Meanwhile, YouLikeLongPasswords would take 2 Quintillion years for a computer to guess, while YOU would remember it a lot easier.

      The problem is that thanks to articles like this, amateur and/or self-taught developers set the max length of the password field to 8 to 10 characters...

      And remember, writing your password down or mentioning it to somebody else is still what makes it the easiest for a hacker to get a hold of it.
