When we go to settings, we will be presented with a list of options, but we need to select the device blocking section and therefore need to click on it. In the “blocking” section we are provided with another list in which we must find the “Pattern key” item. Click on it and follow all the instructions that will be provided to you on the screen. Look at the pictures below.

If you forget it, you will have to proceed with a procedure that will erase all your personal data, and you don’t need this, so remember it and keep it in your head all the time.

Draw a graphic key and press the button on the screen to continue, then the setup wizard will ask you to repeat the drawing, make it exactly the same and press continue again and that’s it. After that, you can check whether you were able to install it or not. To do this, press the power button and turn off the device, after a while turn on the device and a lock should appear at the bottom of your screen. If this is the case, then you installed everything correctly. Don't forget the pattern key, don't harm the device and don't waste your nerves.

How to install a graphic key on Android?

How to install a graphic key on Android?

In order to install a pattern, first of all you need to go to the “Security” section of the system settings and select “Screen lock”.

After that, we come up with a key pattern and draw it on the screen, click “Continue” and repeat it on the next window. Click on the “Confirm” button.

What if you forget?

Enough common problem When using a pattern key, the memory of the device owners is poor. This may result in the key being forgotten and requiring you to reset the key and disable it in the security settings. More details about what to do if you forgot your graphic key are written in the article.

If you are one of those hundreds of millions who “use” a pattern to protect their device from unauthorized access, then you should reconsider your security measures and your attitude towards this option.

My friends showed me the easiest way - they simply took my phone, looked at the screen at an angle and saw stripes of finger movement in dots. Then, after a couple of options, they selected my simple graphic key.

Recently, a more technologically advanced version of hacking was discovered, and programmers came to the conclusion that a complex “pattern” is not a salvation at all. So what is this option?

What is a graphic password? Instead of a numeric password, you are asked to come up with an intricate figure, which must be created by sliding your finger across the screen through any 9 dots. The smartphone can be unlocked by repeating the initially specified figure. If Fedot is not the same, you lose the right to enter.

Previously, phones had passwords. Then more sophisticated ways of protecting against intrusion appeared. The happiness of mankind was expected. But there is a graphic password, but there is no happiness.

Specialists in information security from Lancaster University, the University of Bath (UK) and Northwestern Polytechnic University (Xi'an, China) learned to use computer vision algorithms to select a pattern to unlock Android-based smartphones.

A computer vision algorithm is when a video is first recorded of how the user moves his finger across the screen, and then the program analyzes the finger movements to select possible options screen “choreography” and unlock the device.

The essence of the experiment

To test the methodology, programmers asked 120 people to come up with a graphic key. The volunteers did their best: they changed the direction of finger movement and drew complex shapes.

However, their situation was terrible! For the analyzing algorithm, it does not matter how quickly or how intricately the “pattern” of the key is formed. The main thing is that there is an attacker, there is a video camera, and everything is recorded on video. By “feeding” this video to a program with a developed algorithm, we get options for a graphic key.

It should be noted that the programmers managed to unlock the phone in 95% of cases, and it took no more than 5 attempts. To increase security, researchers advise covering the smartphone screen with your second hand every time you unlock it. You can also resort to deceptive finger movements to confuse the thief's analyzing algorithm.

And here are also videos on how to unlock a smart phone protected with a graphic key:
