Password Font (ttf)
From Director Online Wiki
This font was built to display all displayable characters as circles rather than the astrisk (*) that you find in Director's Password Entry Library Behavior. This font can be used with Director's text or field members, and the built-in Flash Components. If you are going to use it then make sure to disable the Ctrl+C and Ctrl+X shortcuts in the script attached to the password field/text member; if you don't do this then someone can cut/copy the selected text from the field and paste it into any other text editor to get the password.
