What is the most reliable way to lock your smartphone?

Hello everyone, with the advent of NFC, as well as the linking of bank cards and mobile banks to a smartphone, its protection is an extremely urgent issue. A modern phone is easily protected with various types of locks.

Moreover, the more expensive the phone, the more options. In this article, we will consider the main methods of blocking and which one is the most reliable.

• Fingerprint scanner. A very convenient and fast way to unlock. Quality in this case means the speed at which the scanner can recognize your finger and unlock the smartphone. Basically, manufacturers place it on the back cover of the phone, there are also models in which the sensor is built into the display. In terms of security, it is one of the best since hacking it is not so simple. It has a heat sensor, which means that the function will not work with a simulated finger.

• Pin. The traditional method of protection, consisting of a combination of numbers. The best and most reliable. Combine well with a fingerprint scanner.

• Graphic key. A popular way to protect. It can be used with a pin code or fingerprint sensor. The system gives several attempts to unlock the smartphone, then blocks the gadget for a few seconds.

• Password. The oldest way. Allows the use of a set of characters and numbers. Reliable, but not very convenient, since a light password is not difficult to pick up, but a long debt and tedious to enter.

• Face recognition scanner. Uses front camera for recognition. The level of protection is very doubtful, there were cases when the scanner took printed photographs at face value and opened all access to a potential attacker. Of the minuses, I also note that the room must have excellent lighting so that the camera can take a photo of the face.

• Iris scanner. Recognition depends on the level of lighting and the position of the user's eyes. Scanners in more expensive models can work in conditions of poor visibility and from different angles. The shell of the eye should be included in the base of the smartphone.

Output.

Face recognition and the iris scanner - remain secondary - they are not too convenient and reliable. PIN, pattern and password are still the most reliable ways to protect your smartphone from unauthorized use. The fingerprint scanner is also convenient and quite reliable for itself, but it is in mid-range models and still works only in combination with a graphic key or pin code.
