ForScore provides an option to password protect the software.

As explained in the Password Protection section of this manual, this is not a high-security feature, just intended to limit people's ability to mess up your match either through ignorance or a misplaced sense of humor.  You might want to move resetpw.exe somewhere else (perhaps to a floppy disk) if you don't want it accessible to the curious.

If you forget your password and lock yourself out of the program, run resetpw.exe from within the  ForScoreprogram folder (by default, C:\Program Files\ForScore)
