Just what the name say.
This asset will let you hide the chars in an editbox. All you have to do is to add the lib in the trigger selection and then move the trigger "Pass is being typed" to your main trigger folder. Then select the trigger and add the a new condition under the main condition OR- tab there you should add the editbox you wish to make to an password field.
If anything is not clear please ask. I made it cuz i was bored :P
