When you create your account and set up your security options, you are asked to select 2 security questions and provide your answers. If you ever forget your Password, you will need to reset it and will be asked these questions. The answers you provide must be the exact same as your initial answers or you will be unable to reset your password.
As mentioned in the "Password" section, this operation is entirely done by you. Our customer support team cannot help you as we do not have access to these settings in your account.
your Password and PIN Code, we do not store your answers to these questions in clear text. Instead, we create and store a Hashed value of them making it impossible for us to help you if you forget the answers you initially provided.
