I used to use keychain for my passwords. It worked really well until I tried to export data so I could use it on Linux. No dice. The way it looked there used to be an export function but then Apple decided to take it away. I think I'll stick to Bitwarden. Works reasonably well and I can back up my passwords with a simple export.
