Enjoy a comfortable sense of security; a false one, though

“Apple to let you sign up for services with Face/Touch ID instead of passwords” https://mashable.com/article/apple-passkeys/?

It reads "In a WWDC developer session titled "Move beyond passwords," Apple engineer Garret Davidson shows a new feature, allowing users to sign up for new online services using Face ID or Touch ID instead of a password. "

Hearing big players like Apple uttering ‘cryptographic keys’, many people might well automatically feel safe. However, the fact is the addition of cryptographic keys does not make up for the absence of passwords.

The outcome is a false sense of security; You feel as if you were safer when you are actually less safe. This could often be even more detrimental to safety than known absence of security.

Where we need solid security, we need to deploy a solid password for defending the cryptographic keys. Our observation is explicitly outlined here – “Removal of Passwords and Its Security Effect”


Well, you might now ask “What can we do to solidly defend cryptographic keys by our secret credentials?

Our answer is to re-generate the keys from our episodic image memory on the fly as outlined here – “Try and experience the simulation of ‘On-the-fly Key Regeneration’ by yourself”

I've heard of biometrics as a token-based authentication mechanism, but I didn't think anyone would actually use it instead of passwords, on a device that's this vulnerable (according to a certain CS expert anyway, who lives in exile still). Whatever happened to 2-factor authentication?
