A new login technique is becoming available in 2023: the passkey. The passkey promises to solve phishing and prevent password reuse. But lots of smart and security-oriented folks are confused about what exactly a passkey is. There’s a good reason for that. A passkey is in some sense one of two (or three) different things, depending on how it’s stored.
I prefer the yubikey webauthn fido2 non passkey approach. It’s not limited to 25 slots. And if your key gets compromised, or you’re forced to unlock it, there isn’t a list of sites that it works on.
With passkeys, if somebody compromises you, physically, they can see everything you can log into. That makes me feel icky
There are definitely pluses and minuses. It will lock you out after 8 incorrect pins so if it came down to it, you could probably force it to lock pretty quickly.
Can they though? I own a few yubikeys with passkeys stored inside and i cannot query stored logins without entering a pin.
Right, so they coerce you to unlock the yubi key (threats, torture, finger removal, etc) and now they see all your passkeys and what they belong to. It’s a menu of your activity.
