Are fingerprint and facial recognition unlocking really secure?

While biometric authentication offers quick unlocking, it also carries significant risks. Experts recommend combining it with a strong password to protect personal data.

In the age of smartphones, many users choose to unlock their devices using fingerprints or facial recognition for convenience, but experts warn that these are not foolproof security methods.

In fact, fingerprints can be collected from the surface of the phone itself or everyday objects, and then faked to bypass the device's security system.

Furthermore, in everyday situations such as being asleep or being distracted in public, criminals can easily take advantage of this to unlock the phone using the user's finger.

Similarly, facial recognition unlocking also has vulnerabilities, as some devices can be fooled by images or unlocked when the user is not paying attention.

Even more dangerously, once the phone is unlocked, a host of apps such as banking, e-wallets, and social media can also be accessed because they share the same biometric data.

Security studies show that in just a few minutes of access, malicious actors can copy personal data without system warnings, posing a serious risk to users.

A major weakness of biometrics is that it cannot be changed if compromised, unlike passwords which can be reset, meaning the risk of exploitation persists over time.

Therefore, experts recommend that users set long PINs or complex passwords, and combine them with two-factor authentication to enhance device security.
