qMasterPassword

qMasterPassword is a graphical password manager. 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.

There exists compatible software for other platforms, for example Android or iOS.
