About the Account Check feature in Kaspersky Security Cloud Free
There is always a risk that intruders get illegal access to a website that uses logins and passwords for authorization. In this case, your personal data might become publicly available and fall into the hands of phishers or other malicious users. Using the same login and password to enter different websites increases the risk of personal data leakage.
When checking your accounts, Kaspersky does not receive any data in an openly-accessible format, and does not store it. On detecting a data leakage, Kaspersky Security Cloud does not get access to the leaked data, but only provides information about categories of data that may have become publicly accessible.
If the application detects that your My Kaspersky account credentials have leaked to public, you will get a corresponding notification.
Full version of the Account Check feature is available in Kaspersky Security Cloud — Family or Personal.
