Cross-Platform KeePass Password Manager Built with Flutter
Open-source password manager supporting KeePass 2.x (kdbx 3.x/4.x) formats across mobile, desktop, and web platforms with biometric unlock and cloud sync.
AuthPass is a cross-platform password manager built with Flutter that provides native KeePass 2.x compatibility across every major operating system and device. Supporting both kdbx 3.x and 4.x formats, it enables users to securely manage credentials on iOS, Android, macOS, Windows, Linux, and web browsers while maintaining full compatibility with the KeePass ecosystem.
The application combines robust security features—including biometric authentication, keyfile decryption, and encrypted cloud sync—with an intuitive interface optimized for each platform. Users can create, edit, and search password entries, copy credentials with a tap, and sync databases via Dropbox, Google Drive, or direct URL downloads. Android users benefit from native AutoFill integration, while all platforms support secure file handling and protected value management.
AuthPass prioritizes transparency and interoperability. Its GPL-3.0 license and Flutter foundation ensure the codebase remains auditable, while KeePass format compatibility means users never face vendor lock-in. Whether you're migrating from another KeePass client or starting fresh, AuthPass delivers a consistent, secure experience across your entire device ecosystem.
When teams consider AuthPass, these hosted platforms usually appear on the same shortlist.
