How to prompt/hide a password when opening a CMD?

Question

I have some code inside a batch file that when I run it my passwords do get hidden. However I am trying to build it so that I can place the code inside any batch file and you will then need to enter the correct password. Currently you can type anything and be allowed access. I know my code isn't written so you have to type something specific in, that is why I am asking here.

@echo off
set "psCommand=powershell -Command "$pword = read-host 'Enter Password' - 
AsSecureString ; ^
$BSTR=[System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pword); ^
    [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)""
for /f "usebackq delims=" %%p in (`%psCommand%`) do set password=%%p
echo %password%

I wish to keep my code as it is because it currently hides what gets typed, but I need someone to add some sort of password checker.

@tukan No i already have mine hidden i want to make it so you have to enter the correct password using the code i have already written — connorg98, Jul 03 '18 at 10:46
You do the password checking against what entity? Where is the correct password? — tukan, Jul 03 '18 at 10:58
@tukan That is the point i cant figure out how to fit in or were to fit in the password checking. "I know my code isn't written so you have to type something specific in, that is why i am asking here." — connorg98, Jul 03 '18 at 11:08
I don't understand the issue. Your script is accessing where? We don't know your infrastructure. You are trying to check the windows user password or against some active directory server or against some DB? What is your workflow. You need to be specific for us to understand your issue. — tukan, Jul 03 '18 at 11:15
@tukan My script doesnt have to access anywere i am simply asking how to get my code to request a specific password i am not trying to access anything like a DB i want to be able to use my code in any type of Batch file that when i open them E.g A Batch Game that it requests a password through the CMD — connorg98, Jul 03 '18 at 11:20
I see. If you use https://stackoverflow.com/a/36294190/6059896 have it before your Game code you will have the requested password in your variable. You can also do a `CALL get_password.bat` (if you store the batch code and get the return value from that CALL. — tukan, Jul 03 '18 at 11:37

Adding the answer based on comments, so this question is answered:

If you use Batch File command hide password have it before your Game code you will have the requested password in your variable.

You can also do a CALL get_password.bat (if you store the batch code and get the return value from that CALL).

Thank you Connorg98.
