Web browsers do come with basic password managers, which store the login details for the user but it'll be only available in that browser.
Due to this, we prefer to use long and unique login details for every account we have, and eventually it becomes hard to remember all those. At the same time, some among us are well aware about the risk to use the same username and password for all accounts they own since it would be a lot easier for someone to hack into those accounts. In most occasions, most of us write them all down on a piece of paper or use same login details for each and every account, neither of which is safe. But still, managing login details these days is very cumbersome especially if you have multiple login details. We all know that these days digital security plays a vital role and authentication is necessary for pretty much every web service you might use.
