Creating a password for an EA and then hiding its entry

I have a simple password routine for MT4.

if (password != "actualrealpassword")
return(0);

It works fine and stops the EA from running without the password.

I'd like to take it one step further and hide the entry of the password with dots, like when you log into a site. Otherwise the password is visible when entered and just sits in the EX file and logs.

Is there any way to hide the entry of the p/w in MT4?

If you want to avoid the password to show in the input (experts tab and log), a solution would be with an OBJ_EDIT directly on chart. So the password will be entered here and validated by the EA internally without printing in the log.
