BitWarden was a breeze for my parents, there's no difference between the OS autofill and BW... on both iOS and Android, and Chrome for my dad. :shrug:

I have used Bitwarden and 1Password and 1Password is just about seamless while Bitwarden is a little clunky. 1Password is the one I would use for a "family". None of them are really "family ready" as there is always going to be a slight learning curve.

I think the tl;dr here is that there’s actually a lot of excellent choices out there, but almost all of them leave something to be desired in underlying cryptographic strength.
