What types of screen locks are there on Android?

Screen protection in modern smartphones is implemented in several ways:

If there is no protection, after turning on the smartphone screen, you will immediately see the desktop.
A simple swipe or “blind” protects against accidental activation of applications. It can be removed simply by moving your finger up.
Graphic key – there are points on the screen along which the user must draw a convenient picture without lifting his finger. If you enter a picture unsuccessfully several times in a row, access to the smartphone is blocked.
PIN code – in this case there are more combinations, so security is higher. Also, if you enter incorrect numbers, access to the smartphone is blocked.
Fingerprint is one of the newest ways to lock your screen. It is the safest, since the papillary patterns are unique.
Facial recognition is another modern method. Its operating principle is as follows: the camera recognizes points on a human face, if they match the specified ones, the smartphone is automatically unlocked.
Retinal scanner - installed only in expensive models; it is considered the highest level of protection, since the retina is unique.
