Many devices tout fingerprints as security now: laptop computers, cell phones, iPads… but is it a good idea?
Your fingerprints are certainly easier to keep track of than a long, complex password. It’s convenient to unlock your device with a quick tap, rather than having to enter a code. And your children may learn your device password, but are unlikely to get past your fingerprint login. But Graham Cluley shows us just how easy it is to replicate a fingerprint and hack into a device using an ultrasonic fingerprint scanner (here, the Samsung Galaxy S10) with the false fingerprint.
Fingerprints as security on their own aren’t as secure as they seem. As Graham reminds us, you leave your fingerprints everywhere! As both Graham Cluley and Yahoo tech writer Rafe Needleman point out, you can’t get new fingerprints when you need to reset access to your device.
So instead, consider using 2-factor authentication (2FA), with biometric information like fingerprints as only one of those factors.
