Differentiate between authorization and authentication

Question

Differentiate between authorization and authentication?

Answer 1

Authentication validates identity of the user and authorization is the process where we can check whether or not the identity has access rights to a system. Or we can say that authentication is the procedure of getting a number of credentials from users and verify their identity against those credentials. Authorization is the procedure of granting access of the particular resources to the authenticated user. We should note that authentication always takes place before the authorization.
