I think that the idea of passwords has shifted over time. Today we are using more and more accounts, almost every website or service seems to require an account for something. It's impossible to remember strong unique passwords for 300 different websites. Anyone with that many accounts who isn't using a password management system is almost guaranteed to be re-using the same passwords or patterns. Data breaches have also become more common and accessible to bad actors, to the point a script kiddie or hacker could look up your email, see much of your old passwords, and use that to help bruteforce your current password for some important account. Password management defends against this by allowing you to use random meaningless passwords for each website without needing to remember each one. There is no more human element in picking your password, and your old passwords become useless for any would-be intruders.
