Keepass is an open source and highly audited password manager. It stores your passwords locally on your own device add encrypts them with your password. As it is local it can be annoying to sync them between devices.
Bitwarden is an open source password manager that stores your passwords in the cloud. This makes it very easy to use and syncing is easy. All passwords are encrypted locally before being uploaded to the cloud so they will still be safe even if the server is compromised.
You should not use Dashlane because it is proprietary so we cannot verify its protection. Lastpass is also proprietary and it has had two data breaches so we know its security is poor.
