Objective: Secure & private password management, prevent anyone from stealing your passwords.
Option 1: Store Keepass PW file in personal cloud service like OneDrive/GoogleDrive/etc , download file, use KeepassXC to Open
Option 2: Use ProtonPass or similar solution like Bitwarden
Option 3: Host a solution like Vaultwarden
Which would do you choose? Are there more options ? Assume strong masterpassword and strong technical skills
Why not Keepass on a webdav server? Both Keepass on the computer and Keepass2Android can open the file directly. If you save it on one it will merge the changes in any other copies you have open.
