Let me try to explain why you need use above account: Target actually have 2 versions: one is Test & Target (we called Target Classic), the other is Target Standard. You are able to access Target with your Adobe ID, that is to the Target Standard; In your AEM integration experiment, that is to Target Classic which don’t support Adobe ID authentication. In order to make your AEM integration success, Sandbox team provides this general email address and password.
