In-reply-to > how do you geniuses handle all your passwords? People like pword managers but I have like 4 different OSes i use every day and on top of that centralised pword management makes me nervous, upset, and crabby. what if I have to log in from some other system ???

The solutions already mentioned thus far are great. The one I personally use is KeePassXC, with the encrypted database file synchronized to my devices via Nextcloud but obviously you can use whatever file syncing method you please.
I never really used a password manager before doing this; I’m a total convert now though.
