How to protect your smartphone by locking the screen

What is the protection of the smartphone

Smartphones often have a lot of valuable information that is of interest to different types of people. Your data may be of interest to fraudsters, thieves and hooligans, business partners, colleagues and even close people.пин код экрана

Today, smartphones are not just a means of communication, but a completely intimate subject (in different senses). We keep personal records, photos, correspondence in messengers and social networks, bank card numbers in it. Also, many smartphones store Internet bank payment systems to which personal bank accounts are connected.

To restrict access to personal data, they must be protected. If this is not done, then detractors can use your bank card number, view the correspondence, empty the e-wallet, or in any other way harm. There are, to put it mildly, dishonest officers of the special services, and there is a risk of becoming a victim of their actions. In addition, a modern smartphone provides access not only to information stored in the internal or removable memory card. Files in cloud storages, passwords to which are stored in the device, can also become available.

Vigilance when handling a smartphone

The basic rule of data protection: treat your smartphone with care, never forget that it will always be supervised. Keep it with you so that it is difficult to unnoticeably pull it out.

What to do to your smartphone could not climb
Every modern smartphone has a function of protection against unauthorized use.

The most popular method is to turn on the lock screen (or lock the screen, each calling in his own way).

When you complete the action on the phone, you can turn off its screen with the button. But you can configure the phone so that the screen turns off automatically after a few minutes of inactivity. This is not always convenient, but the smartphone screen is guaranteed to be blocked if it is left without your supervision.

Then, when you turn on the screen, an image will appear, requiring actions that only you should know. When setting up an unlock, a choice of protection option is usually provided:

  • Set password;
  • set pin;
  • enter the pattern key.

These software methods of blocking are supported on all smartphones running on IOS (iPhone and Android) operating systems (all others).

And also, there are more modern methods of protection –

  • fingerprint scan;
  • face recognition.

These security options are available on those types of phones where this hardware feature is provided.

It is hardly possible to call any kind of protection ideal. Each of the methods of protection has its pros and cons.

Password on the lock screen of the smartphone

When setting up, you are invited to specify any set of letters and numbers that must be entered each time you turn on the screen of the smartphone.

A plus

It is best to use a long password for protection, which contains numbers and letters of different registers. It will take a lot of time for attackers to select such a combination.

Minus

Are you ready every time in any situation and any condition to correctly type a complex password the first time? Practice shows that this is very inconvenient, so this option of protection is rarely used.

Numeric code – PIN

In this case, you need to assign a 4-digit combination to unlock.

A plus

Easy to remember;
A large numeric keypad is proposed for input – it is convenient to type.

Minus

There are fingerprints on the screen, which can be used to select the unlock code from several attempts.

Screen graphic key

Convenient locking method that is easily remembered visually. But when a graphic key is entered, a fingerprint can remain on the screen, as is the case with a pin code, which can be used to repeat the movement of a finger.

Fingerprint

In this case, you have access to the method of unlocking the device by fingerprint. A very reliable option, which also has its shortcomings. If you cut your finger, the machine may not recognize the prints. Also, if you have a wet hand, then the dactyloscope will also receive distorted information about the texture of your finger.

Therefore, it is recommended:

  • set up unlocking the smartphone screen on several fingers, preferably with both hands;
  • additionally include the ability to turn on the phone on-screen way – password, PIN or pattern.

Face recognition

Also, as with the fingerprint:

  • besides you, no one will have access to turn on the device;
  • make sure that when you turn on, your face is all right – everything will depend on the software recognition capabilities of a specific smartphone.

But let’s not think about the bad.
