The password area of Farm Works was never intended to be used for high security on projects. The main use of passwords was for keeping children from stumbling into their parents' projects and causing damage. As such the processes used for storing and working with passwords is not very sophisticated. We will, however, look into adding this feature to a future version. In the meantime, if you have concerns about someone getting into your project, I would highly recomend that you make regular floppy backups that are stored away from your computer.
