How secure are built-in fingerprint readers in enterprise laptops?

Phone fingerprint devices pretty much suck. Door-style fingerprint readers/locks are also generally crap until you start getting to industrial or military-grade readers. Purely digital ones ala-notebooks vary anywhere from your garbage phone-style quality, to pretty robust and complex readers, dependent entirely upon the specific implementation on the specific notebook. There are readers for computers that require a heat signature within a specified range (it measures on contact with the reader), a pulse, specific fingerprints, and even a movement pattern at a pre-set (by the user) speed. Those are pretty tough to fool, which then puts the burden on the encryption quality of the vault within the machine. Like all encryption, it can be broken with enough time.. but will it be valuable by the time it's cracked is the question. Some implementations are better than others, and they're generally superior in business/industrial grade models than in consumer models as one might expect. That said, they're still just password solutions ultimately, since virtually all of them just replace password entry with an option for biometric access attempt(s) to enter your password for you. Mythbusters tested fingerprint readers on/with XP devices, so many years ago (and WAY worse software and hardware ago). They're still crackable, but not remotely as easily as they were able to do in the above video where the devices and the software were all still pretty rudimentary. It's been a good decade of computing advancement since they ran their tests, it's not remotely that easy these days unless the reader is crap (like on most cell-phones).
