Users feel Password Rage

Pcol writes "The Baltimore Sun is reporting on Password Rage, the frustration users have with the abundance of codes they are required to memorize. Some cope by remembering their passwords with the help of a tune or a phrase, some use three or four levels of passwords with the most complex protecting financial information, and others keep all their passwords in a database - protected by a password. Security experts say that with the increased use of biometrics, our reliance on passwords will lessen in the future. Until then, it's ok to cheat - but wisely."

    Humans are horrible at selecting and using passwords. We have to live with passwords, however, since no other authencation mechanism is good enough to find use outside niches. (Let's face it: when humans interact with computers, we still have to go more than halfway to meet them.) We keep forgetting passwords, because we aren't really good at remembering lexical/numerical data. There are three things people to about this: write passwords down, choose weak passwords and choose the same password for several unrelated accounts. All of these are bad. Very bad.

    Choosing the same password for different accounts is particularly bad. I imagine script kiddies have well-maintained databases of username:password pairs going around. (If they don't, at least the NSA has one.) I remember reading somewhere about how someone could easily acquire a sizeable list of username:password pairs. Set up a website offering free porn. No popups or other annoyances, but require users to create an account before being able to access much. Get word out about your site. Bingo. There you go.

    A lot of websites store their users' passwords as plaintext. If crackers were consceintious enough to update a centralized list every time a website got cracked, I suppose anyone who uses the same password everywhere can be more or less certain that the black hats have got it.

The alternative of remembering all your account:password pairs is simply too much work. Browsers that fill in your password for you alleviate the problem somewhat, but if you browse from a lot of different accounts its still a pain.

Indeed, most of us make fun of biometrics when they are mentioned as a solution to such problems.

    Biometrics are essentially useless for over-the-net identity verification because you have no way of knowing whether the equipment on the other end has been tampered with. There might be no retinal scanner there at all -- just software that pretends there is one and feeds you faked up scans. There is also no way to change your retinal scan if it is compromised, so if someone finds a way to get information on your retina, they can thereafter fake your scan over the net with impunity. It isn't like your retina can engage in a public key authentication protocol with the equipment -- the equipment just makes a measurement, which once stolen can be replicated and by definition cannot be easily changed. Ditto for fingerprint scanners or any other biometric measuring instrument.

    Also, the quality of biometric authentication, even when the scanners are known good and untampered with, is very questionable. The false positive and negative rates are unacceptably high -- measured in percent, not in hundredths or thousandths of a percent. That might be fine for unlocking the weather report, but is completely unacceptable for authorizing a purchase. Worse still, those false identification rates are unlikely to change.

    In short, biometrics are not of any use for over the net authentication. They are only useful in very limited applications, like verifying identity at a door with a guard who makes sure you don't tamper with the equipment, and even then only if the system is verifying your identity based on another mechanism of conveying identity (like an ID badge) rather than attempting to determine who you are based on the scan.

    Determining who you are based on the scan has an amazing error rate -- put a fingerprint scanner up on a door to identify rather than to verify an ID card and one in ten people will just walk in by putting their thumb up to it after being falsely identified as a user of the system. If you actually need security, such rates are unacceptable.

    Anyway, as I said, serious security people rarely mention biometrics in any context, and never for over the net transactions.

    Why, then, do biometrics keep getting press? I'm guessing because if you don't know anything about security, biometrics seem like a sexy idea, and because there are so many startups that have millions of dollars gambled on biometrics and would like people to think that they are going to be of some use in the security world.

Since I make backups of my keychain, having all my software serial numbers stored in one place would make a system rebuild a lot easier since I would not need to track down and re-enter all my software serial numbers.

  27. Strict password guidelines = easier to crack? by Max+Webster · · Score: 3, Interesting

    I wonder if someone will come up with "reverse dictionary attacks". That is, generate random combinations of letters, numbers, and symbols, and then discard all the dictionary words, words with 1 digits, repeated letters, proper names, words with substituted digits, etc. Make the password policy strict enough, and at some point this might become faster than a dictionary attack on a system without so many rules.

    (Part of a rant I originally posted to Ars Technica's forums.)

    I admit that I know nothing about business, but it seems clear to me one of the primary goals should be to to make it as easy as possible to separate willing customers from their money. If people want to give you money, don't make them jump through hoops.

    For example, an alarming number of sites I've visited require me to create an account to buy something. This is a turn-off.

    • For a first-time shopper who may never visit your site again, it's an extra, unnecessary step.

    • An account implies that my name, address, telephone number, email address, and credit card number are stored on file. No thanks.

    • Creating an account means I have to supply a password. This means that I either make up a new password (which I will need to remember but won't should I ever return), or I re-use a password I've used elsewhere. In other words, that's either one more password I need to remember or one more place where someone can steal it.

      I have no evidence of this, but I suspect at least 90% of people re-use passwords. As a consequence, I must ask myself: do I trust your site with my password? (It suddenly strikes me as odd that I would trust a site with my credit card number but not my password, but I do.) Even if the answer is yes, that's one more decision the customer who has already decided to buy something from you has to make; that's one more point where the customer can change his/her mind.

    Please, don't require accounts. Provide them as a convenience to repeat customers, but don't make them a barrier to first-timers. Make the first- timers happy, build up trust, and they'll be more likely to come back.

    (If you do use accounts, it would be reassuring to know if your site hashes or encrypts passwords before storing them.)
