Asterisks in Macro Password

Excel Masters-

Does anyone know how to mask the input of a password used on a macro? I've already got all of the code set up but when I enter the password, it shows the characters and I'd like to have this be private, if possible. Does anyone know how to do this fairly easily? I'm a novice at this stuff, so any help would be greatly appreciated!

Thanks in advance for any help. You guys (and gals) are awesome!
