AuthPass

AuthPass is a free, open-source password manager that works across Android, iOS, MacOS, Linux, and Windows. It lets you store and manage your passwords securely while maintaining full compatibility with KeePass kdbx files. You can unlock your password database using a master password, key files, or both.

The tool stands out with its native platform integrations. On Android, it hooks into the system's auto-fill API to seamlessly fill login forms. It supports biometric authentication like fingerprint and face unlock on supported devices. For synchronization, AuthPass works with Google Drive, Dropbox, and WebDAV services like NextCloud and OwnCloud, keeping your passwords in sync across all your devices.

AuthPass benefits users who need a reliable password manager that works across multiple operating systems without vendor lock-in. It's particularly useful for KeePass users who want mobile access to their existing password databases. The open-source nature makes it appealing to privacy-conscious individuals and developers who want to verify the security implementation.
