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
Enpass uses the open source library sqlcipher (which is an sqlite fork with encryption). So while Enpass as a whole is not fully open source, you can still exfiltrate your passwords with open source tools, should they ever vanish or radically change their business model. You can then use for example enpass-cli.
That gives me enough confidence to trust in Enpass, since they can’t easily hold my data hostage.
