No idea. But historically, although the FBI is in charge of national internet security, they have shown themselves to be idiots when it comes to computers. They were way behind hooking up their own computer systems.
I suspect the technology is beyond them. And I doubt whether anyone who habitually loses laptops is capable of remembering secure passwords, either, without writing them down and probably pasting them on the bottom of the laptop.
(Confession: I can't remember a whole lot of constantly changing passwords either.)
Use a biometrics login. No password to remember, use a thumbprint. And yes the devices can detect things like heat, pulse, etc.
