For digital hygiene, you need to keep your devices clean: conduct anti-virus checks, do not neglect basic security mechanisms, such as two-factor authentication, storing passwords in specialized vaults, updating applications on mobile devices and PCs. Pay special attention to updating security tools. And always think before you transfer personal data. Most leak problems occur when a user registers and transfers their personal data to a huge amount of resources and a gap is discovered somewhere that the attackers take advantage of. For example, a person registers in all online stores where he makes purchases. In this case, the chance of leakage is huge. If there is no urgent need, you do not need to transfer your personal data. For the most part, this will be enough.
