Now, everything from bank accounts to private documents, personal photos, and sensitive conversations is safe on our smartphones. In such a situation, phone security is no less than a challenge. But when it comes to the locking system, the biggest question that comes to mind is whether the fingerprint is better, face unlock is more reliable, or the old but strong passcode.

The fingerprint unlock feature is the most used biometric lock. It is not only fast but also opens the phone in one tap. However, it can sometimes be fooled due to dirty or wet hands. This feature works very accurately in high-end devices, but its reliability is not that strong in budget smartphones.

This feature of opening the phone with the face looks very attractive, especially when the hands are busy. But this technology often fails in conditions like low light, wearing glasses, or wearing a mask. In phones like iPhones, 3D face scanning gives better results, but only 2D camera-based face unlock can be easily fooled.

The passcode or PIN lock system is found in every smartphone and it is still one of the most basic but powerful security measures today. Its biggest feature is that it works even if the biometric feature fails. A 6-digit or alphanumeric password can give a smartphone as much security as a fortress, provided the code is strong and beyond guessing.

Experts believe that relying on only one locking system can be risky. The best way is to adopt a combination of a strong passcode as well as fingerprint or face unlock. Also, it is important to change the passcode from time to time and avoid easy codes.

Your smartphone is the door to your private world. In such a situation, it is wise to adopt a foolproof system for its security. Fingerprint and face unlock are convenient in smartphones, but passcode is still the biggest phone safety feature today.
