Your PIN for your bank card doesn't give anybody access to your bankaccount. that would be terrible. your pin acts as a secondary level of authentication to secure the bank card that is your primary authenticator. just like a PIN in windows hello acts to secure your primary auth method - the computer that's already signed in to your microsoft account.
