About KeePassXC
KeePassXC is a cross platform, open source password manager derived from the Windows application KeePass Password Safe. It runs natively on Windows, macOS, and Linux, storing sensitive data—such as usernames, passwords, URLs, notes, and file attachments—in a single, encrypted database file using the KDBX format (KDBX4 and KDBX3). The project is community driven, hosted on GitHub, and maintained under the NOASSERTION license.
