How is PIN-code removed from Android

A PIN, or Personal Identification Number, is a numeric code used to prevent unauthorized access to your device. It significantly increases the security of user data stored on the gadget. But you have to enter it every time you need to open your smartphone or tablet. This is not entirely convenient, besides, a set of numbers must be constantly kept in memory, which can fail. In such cases, users are looking for options on how to remove the PIN from Android.

What the PIN is used for

The screen lock becomes the first barrier on the way of those who want to get 'inside' the gadget and find out the secrets of its owner. In addition to photos and documents, smartphones and tablets are usually full of accounts, and fraudsters' access to them can lead to irreparable consequences. Including reputational and financial losses.

Young children will not be able to accidentally delete data from a locked phone. If a device is stolen, it may not be immediately usable. The SIM card can also be blocked, and this will not give the thief a chance to use someone else's number and balance.

Some models, especially from Chinese manufacturers, immediately after purchase or update ask: 'To start Android, enter the PIN'. The default is simple, which is recommended to be changed, which can be read about in the manufacturer's instructions. There should also be information on how to do this correctly.

Locking your smartphone correctly

What does correct blocking mean? It should be simple and effective. The PIN code is considered one of the most reliable in terms of security, although this is also debatable.
