Do you have any ideas for a password safe that stores its data locally (an encrypted cloud drive is available for synchronizing), offers clients for Linux, Win and Android and has some amenities like filling in passwords in browsers?
My family needs to learn password safety, and I want to make it easy for them.
I’d recommend Standard Unix Password Store. I’ve been using it for two years and it works fine. You have to solve synchronisation by yourself i use git for it but you can also use rsync or syncthing or anything else. It also has extensions for most web browsers includong firefox and chrome. It has clients for android ios windows and unix like operating systems. You can also use it with dmenu or rofi like i do.
