How Face ID Works: In today’s era, smartphone has become not just a means of calling but also the digital safe of our personal life. In such a situation, security is the biggest question. Keeping this need in mind, companies have introduced face unlock technology i.e. Face ID Presented. But is it really safe? Can anyone fool it? And is it better than a passcode? Let us understand in simple language.
Face ID is based on three-dimensional (3D) mapping of your face. It doesn’t unlock just by looking at the photo, but scans different points of your face.
When you set up Face ID for the first time, the phone creates a digital model of your face. The system matches the same data every time you unlock. It uses technology like infrared camera and dot projector, due to which your phone gets unlocked easily even in low light.
Often people ask whether the phone can be opened by showing a photo or video? Usually not. Because Face ID does not just rely on 2D images, but also recognizes depth. However, in some rare cases, an attempt may be made to deceive the system by using identical twins or very advanced 3D masks. But this risk is considered extremely low for the common user.
This technology is especially beneficial for those who want fast and easy access.
Both have their advantages in terms of security. The passcode completely depends on your mind, but if someone sees or guesses your code then the danger can increase. Whereas Face ID is based on biometric technology, which is difficult to replicate. Experts agree that a long and strong passcode is the most secure option, but Face ID offers a balanced combination of convenience and security. You can use both together for better security.
If you want easy and fast security in everyday life, Face ID is a reliable option. But it is also important to have a strong passcode for added security. Ultimately, your digital security depends on your awareness.
