SLS (Softlanding Linux System) was my first.

I’ve never used Proton Pass so I can’t comment on which is better. However, my wife and I have both used Bitwarden for a number of years and have no complaints. Works with Brave, Chrome, Firefox; works on Linux, Mac and Android. We don’t have Windows or iPhone so can’t comment on those. We can share selected passwords between us.

And it all just works.
