Why People Are So Bad At Picking Passwords 299

mrspoonsi writes "Studies suggest red-haired women tend to choose the best passwords and men with bushy beards or unkempt hair, the worst. These studies also reveal that when it comes to passwords, women prefer length and men diversity. On the internet, the most popular colour is blue, at least when it comes to passwords. If you are wondering why, it is largely because so many popular websites and services (Facebook, Twitter and Google to name but three) use the colour in their logo. That has a subtle impact on the choices people make when signing up and picking a word or phrase to form a supposedly super-secret password. The number one conclusion from looking at that data — people are lousy at picking good passwords. 'You have to remember we are all human and we all make mistakes,' says Mr Thorsheim. In this sense, he says, a good password would be a phrase or combination of characters that has little or no connection to the person picking it. All too often, Mr Thorsheim adds, people use words or numbers intimately linked to them. They use birthdays, wedding days, the names of siblings or children or pets. They use their house number, street name or pick on a favourite pop star. This bias is most noticeable when it comes to the numbers people pick when told to choose a four digit pin. Analysis of their choices suggests that people drift towards a small subset of the 10,000 available. In some cases, up to 80% of choices come from just 100 different numbers."

    As a very well known xkcd points out, a great deal of the problem could be averted if people weer encouraged to use long passphrases with spaces and everything rather than a pass'word'. password as a concept was good enough for the time of it's popularity, to defend against people typing their way into someone else's account. When the model fell apart in a world with much more automation and network connectivity, the 'fix' was 'keep length about the same, but toss some numbers and maybe some punctuation in there'.

    The madness comes in when a great deal of the sites I visit put a 12 character *maximum* on a password for their site.

    My personal strategy: base64.b64encode(os.urandom(12)) for every site and store the values on a couple of my devices with a phrase that is about 32 characters long (but easy for me to remember and easy to type). hashing a master key with the domain to generate passwords like some chrome and firefox plugins (password hasher) can do is similarly nice without having to worry that you won't have access to the copy of the database.. Of course, the annoying thing is my 16 random numbers and letters frequently fail the 'complexity' check and I have to add some punctuation character to it.

    Please tell me no one is surprised by the general conclusion (haven't we been here a time or ten before?) of these studies. Add to this the corporate or government attitude demonstrated so equivalently here [xkcd.com], the lack of effective computer security training, including a complete failing of organizations to have or heaven forbid enforce policies about password practices and you've got a pretty pickle.

    Sadly, it took the recent Adobe compromise, to get me to finally start using a password wallet and use different passwords for each Internet service I use. Have to admit I was stunned, by the number of accounts I had when I got through most of the sites I access.

    After hearing a few disturbing stories from my wife, about how computer security and passwords are treated at her place of work, I stepped up my training for her and her co-workers that will listen. Based on what I've heard from her the choice of poor passwords is the least of our troubles.

    • Passwords on sticky notes on monitors.
    • Passwords shared with co-workers, that have not been granted access.
    • System does not require default password to be changed.
    • Default password is a known pattern.
    • Techs routinely ask users for passwords
    • Co-workers say, "Just give them your password".
    • And so on . . .

    Unless the underlying problem of poor culture surrounding computer security is changed and an understanding of the associated risks is cultivated, it won't matter one whip whether users can choose "Good Passwords TM".

      complete failing of organizations to have or heaven forbid enforce policies about password practices

      Most of the time the problem is the opposite. Absurd policies and a delusion of the password being important to the user. And lately, the retarded concept of the security questions that the user cannot choose (or can choose from a set or around the same 10 in every site).

      For like 95% of the sites I don't give a shit if my account if hacked. I use the same password for most of those sites (if they are too retarded with requirements I might add a few 0s or #s at the end). If you make me change the password even if once a year then I'm not going back to your site because I don't care much about it in the first place. So I'll forget the new password.

      -Passwords on sticky notes on monitors.
      -Passwords shared with co-workers, that have not been granted access.
      System does not require default password to be changed.

      None of these are user problems. They are system design problems which I can translate to this:

      - They make me change the password every 90 days, so I have to write it down.
      - Danny needs to access credit card information because it's part of his job to do refunds but they won't give him access because for some reason that also means they have to give him access to XXX (they have one permission for two things) so I have to type my password at his terminal 10 a day. I cannot be interrupted that much, or I might not be around, etc, so I just let him use my password.
      - My sysadmin uses the same default password for everyone.

    If we start with the asumption that that passwords must be memorized somewhat, we are better remembering things with an attached meaning than something random, and those meanings make usually bad passwords. But, we don't need to remember all passwords, there are password managers for making and storing a bunch of meaningless, secure passwords, and for the keys you must remember (the password manager one at the very least) there are some mnemonic tricks [xkcd.com] that can help to have safe enough passwords.

    On passwords, what was once thought to be good password security is no longer true. The length of a password matters more than diversity and given the right instructions, can be much easier to remember than complex passwords.

    My current suggestion for passwords is this: Pick three (or more) random words. mongoose, screwdriver, automobile. Now you have a password you can remember, but is very hard for a computer to "crack" and you only have to remember three things, as opposed to memorizing eight (or more) things that don't make any sense.

    And, to make it unique for each System you log in to, add in the name: Amazon Mongoose Screwdriver Automobile, or Ebay or whatever.

    "people are lousy at picking good passwords"

    This begs the question. There is some reasonable expectation that people should learn to properly use the tools of modern society, but in the end, the tools should serve the people, not the other way around. If your car pulled to the left, would you say you were lousy at driving in a straight line? No, you'd say your car was out of alignment and get it fixed.

    A password is something we're expected to remember, but we're wrong to pick words or numbers that might be easy to remember, such as familiar names or dates. Even if you say pick a system of choosing passwords to remember rather than an individual password, that's impossible. Every different system and site has different password requirements, so no single easy to remember system will work for all of them.

    "You have to remember we are all human and we all make mistakes"

    Yes, and Mr Thorsheim's mistake is assuming the issue is with the people who are using the system and not the people designing the system. The truth is,

    "password systems are lousy at serving people."

    (as an aside, WTF is up with systems that do not allow special characters in passwords? Are they worried about SQL injection? If that's possible from a password field, the system is FUBAR.)

  • I would hope the list of allowable PINs is shorter than that. The 10 possibilities with the same number repeated all the way through should be disallowed (and usually are), as well as 1234, 4321, and anything else with four consecutive digits. While taking those 24 possibilities out doesn't dramatically reduce the number of possible PINs (only 2.4% reduction) it is still a list of less than 10,000.

    Every time I see articles like this, I feel compelled to bring up the solution I'm using, which is (so far) the single best solution I have been able to find.

    It's called 1Password. Runs on Mac, Windows, Linux (read only I think), iOS, Android, and has plugins for all major browsers.

    It records your login details for you, has a password generator that you can customize in various ways, and stores an AES encrypted archive on dropbox so that all your devices can sync together.

    Now I can safely create new logins everywhere with abandon, because I'm not afraid that if one service is compromised (*cough*Adobe*cough*) I'm not afraid something else is at risk.
    It can generate passwords up to 50 characters in length with your choice of number of digits and symbols. It can even make easily pronounceable passwords if you need, and avoid ambiguous characters (eg O (oh) and 0 (zero) ).

    It's a little pricey, but IMO it's worth every penny because there is no other product out there that is this easy to use, AND supports so many platforms all at once.

    • I use a similar product called Password Safe. http://passwordsafe.sourceforge.net/ It lets you store your passwords in an encrypted file with a master password. It can also generate passwords for you (in a configurable manner so you can go from "p%qLr%&Vb9" to "+R0WeeDUck" to "PiGhtEdraN" and anywhere in between - and yes, those were Password Safe generated).

    The proper way is to use a good password manager with the following features:
    1) cloud-based sync, so you can access it from any computer or mobile device
    2) multifactor authentication, such as a USB stick or a grid or biometrics
    3) a configurable password generator (i.e. you can choose length, complexity, etc.)

    I use LastPass and like it enough to have bought a year's subscription for $12, but there are other good choices out there like 1Password, or you could homebrew up something with e.g. DropBox + KeePass or Google Drive + TrueCrypt + something that can read TC volumes on iOS/Android.

    Generate a different random password for each site needing an account, as complex and as long as the site will allow for, and with LastPass at least you can attach a note to each site's entry so you could enter random line-noise answers for security questions like "What is your mother's maiden name?", thus making crackers work much harder. I've also got LP set up for multifactor authentication and with a strong master password.
