KeePassDX is a password and passkey manager for Android that stores credentials in encrypted database files compatible with the KeePass format. It offers autofill, biometric unlock and one-time password support. It is an alternative to vendor-hosted password vaults for users who prefer to keep their encrypted database as a file under their own control. The app is distributed through app stores and F-Droid and is developed by Kunzisoft, a company in France.
The source code is published on GitHub under the GPL-3.0 licence, or any later version, so organisations can inspect and build the app themselves. The project describes KeePassDX as a local manager of encrypted database files. For a European organisation the main question is therefore where the database file is stored and how it is synchronised, rather than the jurisdiction of a service provider.
