Authentication is the process of identifying users based on their credentials, i.e. user names and passwords.
Authorization is the process of determining whether an authenticated user is allowed to access a specific resource. Even though a user is authenticated, he/she might not be authorized to open a file or web page

Authentication is the process that allows an application to verify that a person (or another application, smart card, and so on) is the one that it claimed to be when connecting with it.

Authorization defines a user's rights and permissions in a system. After a user is authenticated, authorization determines what that user has the authority to do on the system. Authorization, therefore, is typically assumed to follow authentication.
