So that I can monitor your account premium membership regularly and some technical concern about the payment method.

Why do you want to change the password? I will not hack your account or check what movie are you watching. If you are a trusted member and really interested to buy then I can make an exception for you. You can change password.  

Besides that, I have a 1-year warranty for it.
