Password saving batch file for unlock/login

Is there any way to create a password then have that newly made password stored in the same batch file as the login code and keep it as that new password???? Here's a visual example of what i mean

Typing in the incorrect password

Typing in the correct password

Setting new password

Is there any way to do this with 1 batch file entirely without having to make another one to save the data?? I am trying to do this on windows 10. I am trying to do this so I dont have to do a preset password like: if %pass%== 12345 goto Login instead I want it to where every user can create their own special password without needing to edit the code
