You may get confused when someone talks about authentication and authorization. In the first instance, you may think they are one and the same. This video tries to explain the difference between the two terminologies.
Authentication establishes who you are (or what is your user id). Authorization establishes what are the activities you are allowed to do in your account. In AWS, authentication is done based on user id or role. Authorization is done using permission policies.
