Passwords are bearer credentials and as such, they are not a meaningful layer of defense when in the custody of even a modestly competent system administrator.
As I'd said, you need to look no further than annual threat reports to see that credential theft is the most common avenue of abuse - by a lot. Hardware assertions, on the other hand, which in WebAuthN standards are also bound to domain origins, simply remove this risk entirely. Let me repeat: you cannot phish a WebAuthN assertion. Yes, you can pull off a physical attack, but at this point of the game, it is over because the adversary could just implant a bootkit, keylogger or backdoor on your valuable system.
The threat landscape certainly changes but the economics of computer fraud and abuse remains largely the same: attack the most vulnerable link in the chain for maximum profit for the least amount of cost - the human and her portable password (and other forms of exportable factors, roughly in order of security: SMS-based, HOTP/TOTP apps, email magic links, Duo-style "confirmations").

Again, you are avoiding my argument. Passwords, even pin codes have been a meaningful layer of defense for half a century. You can argue that they are weaker and propose stronger methods such as paddhphrases but you arr arguing against passwords when your real argument is against "what you know" as a factor of authentication. > As I'd said, you need to look no further than annual threat reports to see that credential theft is the most common avenue of abuse - by a lot. Are you a middle manager or executive by chance? Because I respond to incidents as a matter of routine and I very much know how much passwords get phished or cracked. You know what solved the problem: adding even the weakest layer of authentication like SMS. Now, there are many better altetnatives for a second factor of auth other than SMS as there are for passwords as what you know being a factor and I am open to that discussion. But what you are saying is you don't get why a weak layer of defense is needed so you want to get rid of it. > The threat landscape certainly changes but the economics of computer fraud and abuse remains largely the same: attack the most vulnerable link in the chain for maximum profit for the least amount of cost Again, it's not a chain. Your mindset is a flawed way of thinking carried over from physical security (think "cyber killchain), which is perimeter focused, that's where the chain analogy comes from. Modern security, having learned from the past few decades is such that you have many layers of chains. The user's knowledge, as weak as it is, is one such layer. Removing it plain and simple is a reduction in your security posture. See, the critical thing you need to get is the relationship between layers od chains as opposed to links in a chain is complementary not symbiotic. Persistent threat actors will get past any layer of defense. If ransoming your company gets me a few million dollars, as a criminal there is not a whole lot I wouldn't do including physical attacks (there are even untargeted campaigns where threat actors drop or mail USB drives en masse). > the human and her portable password (and other forms of exportable factors, roughly in order of security: SMS-based, HOTP/TOTP apps, email magic links, Duo-style "confirmations"). Great, guess what that means? They spent all that time and effort to get past a password and now they face a yubikey. The difference in cost to threat actors is at least geometric. They can't just steal a yubikey or compromise your phone, now they also have to steal or guess your password. By removing user knowledge as a factor, you are making it orders of magnitude cheaper for a threat actor. And you think that is fine because the latest and shiniest methods of authentication, unlike past solutions will never ever be defeated and you will never face insider threats or threat actors willing to spend more to profit off of you.
- 1101010010 4y agoStealing or guessing a password is infinitely easier than compromising a Yubikey or otherwise hardware-based authentication factor. This is a demonstrable fact and any argument to the contrary is simply pearl clutching. I challenge you to find even a single incident resulting from a compromise of this 2nd factor, until you do there's nothing to discuss. And because you don't find it, it will ultimately demonstrate passwords are not even necessary when accounts are protected in this way.
- _8j50 4y ago> This is a demonstrable fact and any argument to the contrary is simply pearl clutching I agree. Lookup what a strawman argument is. No one made that claim. > I challenge you to find even a single incident resulting from a compromise of this 2nd factor,... Friend, do you read comments before replying to them? That is exactly my challenge to you. Passwordless usually means getting rid of 2fa and using one or more "next generation credential providers".
- 1101010010 4y agoI'm thoroughly convinced you don't understand the U2F/WebAuthN standard, which makes intelligent discourse about the topic impossible. Good luck with your studies.
- _8j50 4y agoWe weren't talking about those two standards alone and you haven't brought them up as examples either. All i have learned from you is you use strawman arguments. Ok, what part of U2F requires users to remember a secret? I have seen passwordless accounts you can take over simply by controlling a yubikey. I hate it when people seem to argue with me but argue against strawmans they're inventing. I agree, discourse here can't happen.
- wprl 4y agoThanks. I learned something. Even if passwords are a weak form of security, they add an extra Ayer that would make it much more difficult for an attacker. They don’t have to be the only layer of security, and would still be good as an extra layer on top of hardware keys and/or OS keychains. Very interesting.
