How do I have my .bat file also type in a password for the program it's commanded open?

@echo off (Or on)

setlocal enableextensions enabledelayedexpansion

set lines=1

set "line1=*PASSWORD*"

for /f %%a in ('"prompt $H&for %%b in (1) do rem"') do set "BS=%%a"

for /L %%a in (1,1,%lines%) do set num=0&set "line=!line%%a!"&call :type

pause>nul

goto :EOF

:type

set "letter=!line:~%num%,1!"

set "delay=%random%%random%%random%%random%%...

set "delay=%delay:~-6%"

if not "%letter%"=="" set /p "=a%bs%%letter%"
:: adjust the 3 in the line below: higher is faster typing speed

for /L %%b in (1,3,%delay%) do rem

if "%letter%"=="" echo.&goto :EOF

set /a num+=1

goto :type (Take this out if you don't want it to repet)

I can successfully start my game program with this .bat file

start /d "C:\Program Files (x86)\(PROGRAM FOLDER NAME HERE)" (PROGRAM.EXE HERE)

or a more easy to read example

start /d "C:\Program Files (x86)\balloons" ball.exe

It's great! However, this game requires me to log in. It automatically has my username remembered but it doesn't have the password. I want the .bat to also type in the password and hit the "enter". ( also if you could show me with the .bat that types the username and password, that would be great too! )
