Is Face ID bad for privacy?
Data breaches involving facial recognition data increase the potential for identity theft, stalking, and harassment because, unlike passwords and credit card information, faces cannot easily be changed.
Is Face ID safe from hackers?
Face ID eliminates the need to manually type in your passcode, making it much more challenging for hackers to steal your information, even if they get your phone. It's easier to steal (or even guess) a passcode than to fool your iPhone's camera by faking your unique facial scan.
Is Face ID safer than fingerprint?
Therefore, if given the opportunity to buy an Android phone that has facial unlocking or fingerprint security, if you're after safe use of your phone, it's likely better to try fingerprints.
