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.
