in my understanding,
in their office, they know the password of their internet connection,
therefore they can setup the password in the AMT,
so they can access the devices remotely,
but after the products being distributed all over the world,
then each are connected to different wifi router with different passwords,
therefore they need to set up another wifi password to the AMT,
in order for the AMT to be connected with the internet,
so that they can access it remotely,
but then how do they know the password ?
also how do they access it remotely to re-setup the password ?
