Passwordless as a concept needs to die along with biometric auth.
You have really good newer methods of auth. Instead of selling them as good MFA alternatives security vendors decided to replace passwords because that differentiates them more. But in reality, the layer of defense "what you know" should be complemented not replaced. A reduction in security being sold as a feature is dishonest and harmful.
- jaywalk 4y agoPlease explain how this is a reduction in security.
- hsdropout 4y agoThey are pointing out that while the "something you have" factor may be stronger than "something you know", multi factor is still better. I agree. Also, passwords are decentralized, whereas passwordless puts the power into fewer hands, so this too reduces complexity for attackers. 2FA>1FA
- PassageNick 4y agoThe threat surface of a password based system is like Lake Superior. The threat surface of a passkey based solution is like a small puddle after a rain. How is there a "reduction" in security here?
- _8j50 4y agoDoesn't work that way. Passwords are inferior but still a strong layer of defense. You are putting all your eggs in one basket again. The lesson from passwords is that a single factor of authentication is inherently inferior to multiple factors of authentication. From a threat actor's perspective, even a yubikey is a matter of one well planned attack (physical, compromised host,etc) and by nature newer factors of auth don't get treated with hostility like with passwords. They are better than passwords but what I see is people moving away from MFA to only a yubikey for example. Like you are now one lost yubikey away from your whole company getting owned lol.
- PassageNick 4y agoPasswordless is MFA -- something you are and something you have. I'm not a yubikey expert, but I don't believe that losing your Yubikey will open up your company to a breach. For a typical passwordless solution, losing your phone isn't a risk, given that no one can reproduce your face or thumbprint.
- _8j50 4y agoYour face and thumbprint can easily be reproduced. There is even a guy that took a photo of a politicians' finger from a mile away and used that to forge their fingerprint. Even without going technical your dopplegangers can bypass face auth lol. You can guess spray pins and push notification codes. The one thing you can count on is someone will find a way around any good passwordless solution. For example, there is a "rdp in browser" phishing where a browser in the attackers vm does the actual auth but the user thinks it is in their browser so most passwordless methods are defeated by cookie theft like that.
- PassageNick 4y agoIf you can take a photograph of someone's fingerprint and reproduce it, how, exactly, does one use that?
- PassageNick 4y ago....and can you explain the cookie theft thing a bit more?
