I don’t need convincing arguments. A software password manager is a single point of failure, as the story demonstrates. It’s a dangerous external dependency with alluring convenience.
Until mind reading becomes reality, nothing will ever be as secure as human memory.
- scrollaway 5y agoAnd your mind, or whatever algorithm you came up with, isn't a single point of failure? You will never be one thousandth as good at securing hundreds of password as the most robust tools we have today. You may be good at remembering a couple of long, random passphrases. You can use those as a master password / encryption key. The software mentioned in the article is not a particularly good or trustworthy password manager, so no it doesn't make sense to put it in the same lot as the actually-good ones. Or to put it another way, if I come up with a crappy off brand version control software and backdoor it, that doesn't reflect badly on VCS, it reflects badly on me.
- tediousdemise 5y agoI admit that there might be password managers out there that provide sufficient security for some users’ threat models, but I wouldn’t trust such a sensitive compilation of data on any computing system, especially ones with network access. If I used a password manager, it would have to be on an airgapped and password protected system, making it essentially useless for me. For me, it’s easier to memorize a password/salting algorithm that generates unique passwords to the website or service I’m using, so that I don’t have to actually memorize any passwords—only the algorithm.
- scrollaway 5y agoThis is a common take on password managers but in practice it doesn't really hold, because humans are bad at security and good password managers are really fucking good at it. That's not to say there aren't weaknesses to the password manager model, but you're overestimating them and underestimating the ones in your scheme. I also invite you to read my response above to someone else regarding the security of such an algorithm: with some examples, brute forcing an algorithm is easier than brute forcing a master password.
- hackinthebochs 5y agoThe issue is that password managers skew the cost/benefit analysis of an attack, thus altering the risk profile for the individual. As long as your password creation/storage method is strong enough to thwart low motivation/low resource parties, you may be better off than being in a very attractive pot of millions of credentials.
- scrollaway 5y agoThat is a fair point, but keep in mind the risk of NOT using one. Most people won't have a "strong enough" storage/creation method. I'd argue even those who think they do probably don't. To me the whole conversation sounds like this: - An unknown, low security bank was broken into. - This proves storing your money in a bank is a terrible idea! This is why I keep all my money in my home. - No that's definitely a worse idea. Storing your money in a bank is the most secure way to keep your money. It's not infallible but- - Yes but alone i don't have that much money... It's a lot more attractive if it's in a big oot everybody else's. - Well no, most good banks invest a lot more in security than you ever would or could. - No it's okay, because I put it in a box and I have a lock on it. - Like a safe? - No. I don't trust safes either.

- albuic 5y agoIt does not. It shows the failure of one ONLINE and CLOSED SOURCES password manager. Both of those can and should be avoided.
