@tokyo_0 @pojntfx the information is a little bit to hidden at the bottom of the post:

Fortunately, if you want the level of high security passkeys can give you without the strings attached, there is actually an even more secure solution: security keys, such as a YubiKey. These are basically just physical passkeys that you can carry around with you and use alongside your other devices. They are also part of the FIDO Alliance’s WebAuthn standard, but because they are entirely self-contained their remote attestation requirements don’t have to spill out and lock down your whole operating system.

So, "Does this apply to the little USB ones as well?":

No, you are safe with your hardware tokens and yes, they are superior to passwords AND cloud passkeys.
