What's the difference between Authentication vs Authorization?

Authentication is the process of verifying the identity of a user, process or device, often as a prerequisite to allowing access to resources in an information system.

If you are trying to enter a country, the border officer is essentially performing some form of authentication: he is comparing the photo on the passport with your appearance, checking your eye color, height, etc. In other words, he is trying to verify your identity.

Authorization is the process of verifying that a particular action or service is approved for a specific entity. Although you might be logged in, you might not have the permission to perform specific actions (e.g. revoking access for a particular user).
