All cheap smartphones have a fingerprint sensor but all laptops dont have one. Is it because of security concerns or spacing reasons?
What about the fact that fingerprints make great usernames but trash passwords? Perhaps the poor security and extra hardware and software are enough to discourage makers, they can add a variant with a FPS and if that doesn’t sell at all they won’t make many others.
Because you very rarely need to actually log in on your laptop. You lock and open your phone dozens of times per day, but you’ll probably log in once or twice on your laptop and that’s it. It’s not a feature many people would care about.
I always lock my computer when I walk away from it so my dog can’t start hacking the CIA.
I use the TouchID on my MacBook several times a day because it unlocks the password manager and wallet.
I unlock my 1Password vault(s) with fingerprint, so it’s much more useful than just logging into the laptop. which at work I log into many more times a day than once or twice.
The following is just my own assumptions, take with a grain of salt.
Phones are often taken out to perform a quick task, then stashed back in a pocket/bag many times a day. As such, being able to unlock a phone quickly is a rather useful feature.
On the other hand, laptops are usually taken out to be used for larger tasks, and as such, do not need to be unlocked as often.
Fingerprint scanners add less value to a laptop than they do a phone.
