The main advantage of using Kaspersky Password Manager is that it lets you have all your passwords and usernames (sometimes just as problematic as the passwords) perfectly managed and always on hand. So on hand, if fact, that when you visit one of your websites, all you have to do is click once to log in.
Another really interesting feature is the possibility to generate random passwords to register with any website. The program takes care of remembering the password, while you can simply click on it to log in automatically. Kaspersky Password Manager is a really interesting tool for anyone who has a lot of different accounts on all different websites (which, nowadays, is most of us).
