I love keepass, and use it with all of my systems. I have the database on my personal nextcloud instance (but you can use One Drive / Google Drive / DropBox) and encrypt it with not only a passphrase, but a keyfile. I can access the database from my phone, desktop, laptop, and other devices. Since you're also using a keyfile to encrypt it, it doesn't matter if another party gets the db file and even your passphrase, since only a device that also has the physical keyfile can decrypt it.
