You can link accounts in Kaspersky Password Manager in the following cases:
If you use the same account to log in to one or more websites and an application (for example, you check email via a website and via a dedicated application, or use a social network password to log in to an application).
If you use the same application on different devices, and data synchronization results in a different account for the application on each device.
If you have linked several accounts, you can change their logins and passwords simultaneously.
