Every company that creates websites or apps for Login with Amazon gets the same
user_idfor a customer. However, when a customer logs in to another company's app or site, the
user_idwill be different. This is so
user_idcannot be used to track customers across the Web.
I'm not sure whether I understand this correctly,
It states that every company gets the same `user_id` however it kinda contradicting this statement "the
user_id will be different"
Would you mind giving me a more elaborated example?
