What is the difference between authentication and authorization?

 Answer:

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 means who you are. Authorization means what are rights you have something like that you have been permited to access specific web page or resources

Authentication:

An authentication system is how you identify yourself to the computer. The goal behind an authentication system is to verify that the user is actually who they say they are. There are many ways of authenticating a user. Like Password based authentication, Device based authentication, Biometric Authentication, etc.

Authorization:

Once the system knows who the user is through
authentication, authorization is how the system decides what the user can do. A good example of this is using group permissions or the difference between a normal user and the superuser on a unix system.
