No password char option was implemented because all the HMI security was supposed to go through the built in system. Here is one way to implement a password char AnalogNumeric Box.
You need to install the font included in the PasswordFont folder and implement the InputValueChanged method in the screen script. Set the font for the AnalogNumeric control that you will be using to input the password to the password font. When the user inputs the password that font is used and just displays '*'. Once the password in entered the value entered gets transferred to a tag and the text in the AnalogNumeric control gets set to '*'. That way the user can not copy/paste the password.
I am looking to see if there is an easier way.
