What Martchus Password Manager is

Martchus Password Manager is a free, open-source password manager for Android, Linux and Windows. It offers a Qt graphical interface and an interactive command-line interface, with the command-line build available without the Qt GUI. The project describes AES-256-CBC encryption through OpenSSL and stores data in ordinary files rather than a cloud service. Its README suggests Syncthing for synchronization. Desktop screens use Qt Widgets, while mobile screens use Qt Quick and Qt Quick Controls 2. Linux downloads include packages or binaries for several distributions and generic systems, and Windows binaries are provided. The stable Qt 6 Windows version requires Windows 10 version 1809 or newer; an older Qt 5 version may work on Windows 7 but is not regularly checked. Android requires version 9 or later on aarch64 or x86-64 hardware. GitHub Releases lists version 4.4.1 assets for Android, Linux and Windows. Generic Linux and Windows binaries are signed with the listed GPG key, and code is GPL-2-or-later.
