Interesting point. I never really thought of the laptop as something you have but it certainly is.

I will say that a security key is far easier to carry on you in more situations than say a laptop is and certainly a desktop. And the key, depending on how it is used to secure the device, may help mitigate brute force password attacks in the event that the device is stolen.

An argument could be made for defense in depth but for most people I would guess the amount of added security is probably not super beneficial and for those where it truly does matter then securing physical access to the device is probably more important any way.

Agreed, I wasn't trying to say that your computer counts as enough of "what you have" to third parties. Is why I don't think it counts for most accounts you have access to.

That said, your phone is growing to take that privilege.
