The documentation recomends using the OBJECT SET FONT command to set a variable to the password font; like this:

OBJECT SET FONT([Users]Password;"%password")

However, there is a second way. In the Property List you can set the font under the Text section. The font %password does not show up in the drop down menu but it can be typed in manually.



This will have the same affect as using the OBJECT SET FONT command.
