1Password - password manager with cross platform sync.
I’ve used Bitwarden but it’s very barbones. In the past I always used 1Passsword because it’s full featured but I was on Mac at the time and 1Password was Mac only.
I then moved to Linux and used Enpass, then Bitwarden. At last 1Password realised they needed to go cross platform and they have a native Linux client. So I moved back to them
Easily the best and most secure and full featured password manager that’s ever existed. I highly, highly recommend it if you haven’t tried it.
