qMasterPassword

qMasterPassword is a password manager based on Qt. Access all your passwords using only a single master password. But in contrast to other managers it does not store any passwords: Unique passwords are generated from the master password and a site name. This means you automatically get different passwords for each account and there is no password file that can be lost or get stolen. There is also no need to trust any online password service.

See this introduction page to get more familiar with the concept and reasons why to use it.

The algorithm is described here.

The Spectre home page also contains other compatible software for various platforms, like Android or iOS.

qMasterPassword is developed on Linux and also tested on Windows. For Windows there are prebuilt binaries under releases.

Dependencies

• Qt 5.2 or higher (see branch qt4.8 for older Qt version support)

• Linux/OSX: libscrypt library

  On Debian/Ubuntu, it is available as libscrypt-dev.

  On RedHat/Fedora, it is available as libscrypt-devel.
