On January 22, 2018, Amazon Go, a store that uses cameras and sensors to detect items that a shopper grabs off shelves and automatically charges a shopper's Amazon account, was opened to the general public in Seattle.[54][55] Customers scan their Amazon Go app as they enter, and are required to have an Amazon Go app installed on their smartphone and a linked Amazon account to be able to enter.[54] The technology is meant to eliminate the need for checkout lines.[56][57][58] Amazon Go was initially opened for Amazon employees in December 2016.[59][60][61] In August 2018, the second Amazon Go store opened its doors.[62][63]

I do not like the security of this apps. By default any one in my home can just open it up and start buying things on my account. I would like it to just add things to my cart on the TV and them buy on "My" Computer or "My" phone. I know you can setup a PIN for "videos, purchasing and certain types of content".But, you then need to enter the PIN for $0 videos. Also, anybody with access to the Fire TV remote can just install the apps and start buying things, no pin, no password, just because you have a Fire TV setup on your account. Amazon you need to have a separate PIN for Buying videos, parental control (ratings), Apps and Shopping. And by default the app should setup a PIN.
