In this window you can link web accounts and application accounts with other web accounts and application accounts (ones that have the same login / password combinations).
You can link accounts in Kaspersky Password Manager in the following cases:
If you use one and 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.
This window also shows all accounts linked with the selected account. Changes made to the selected account are applied to all web or application accounts that are linked with it.
