Comment on Google will now make passkeys the default for personal accounts
alvvayson@lemmy.world 1 year agoYou should really read up on multi-factor authentication and Web-Authn.
Your problem seems more that you don’t trust Google to store your private keys in their cloud.
And that’s fine. You don’t have to do that. But don’t be confused to think that’s the only option. You can buy a yubikey or a Trezor model T if you prefer.
Passkeys are just a marketing term for Web-Authn. When you use asymmetric keys for other purposes, it’s not passkeys.

I missed the part where I said I don’t trust Google. You seemed to have ignored everything of substance in my response, namely putting a password on the passkey doesn’t remove passwords and the extension of things like FIDO2 beyond web auth.

I didn’t ignore it, I said you need to read up on the basics.
Protecting a private key with a password is totally different than authenticating with a password and you don’t see to understand that difference.

It doesn’t get rid of passwords, which is what I said when I said it was a disingenuous claim. It just moves the attack surface, like I said before. You haven’t bothered to demonstrate even a passable understanding of my original comment and the security issues I raised as a security professional because you appear to want to dunk on me. I’ve been having this conversation for years so sorry not interested.

That suggestion up thread to read up on how webauthn/CTAP2/FIDO2 works?
It’s a good suggestion. I would take it.

Sorry, you’re just wrong. It does get rid of passwords as the authentication mechanism and replaces it with a private key.
Claiming otherwise is being ignorant on how it works.
Even if someone knows the password to your phone or yubikey, they still need your phone or yubikey. Knowing just the password is useless. If you are a security professional, you would know this is called a possession factor.
If you’ve been having this conversation for years, you really ought to know better.
