What Keeps People from Using Password Managers?

I didn't use one until I got one for work (1password) and realized how convenient it is to keep track of passwords across devices. Around the same time period, for me anyway, there seemed to be a proliferation of SaSS or at least non-trivial online products I used that I needed a login for. Meaning it's become impossible (or at least impractical) for me to manage passwords on my own.

If I were trying to convince someone to use a password manager, I'd try and time a free trial with some kind of life event that required a bunch of new signups to online things, so they could see how valuable it is. Examples might be starting school, or immigrating.

many do today they just do not know it. on phones alone they are integrated. transfering and having them accross plateforms is a bit more tricky with those though.
