Enter a website that uses different logins for your various domains, for example:
http: \\ domain \ site1
http: \\ domain \ site2
Kaspersky Password Manager will provide the same username and password for both sites, because the domain is the same. And it will not allow you to save a different username and password for that same domain.
Kaspersky Password Manager should recognize the different sites or allow multiple logins for the same domain and provide an option to select which login you would like to enter on that site.
