Difference between Authentication and Authorization ?

Answer Posted / rachana devi

In authentication, the system or the web application identifies its users through the credentials they provide. If it finds that the credentials are valid, they are authenticated, or else they are not.

In authorization, the system or the web application checks if the authenticated users can access the resources that they are trying to access or make a request for. In other words, it checks their rights and permissions over the requested resources. If it finds that they can access the resources, it means that they are authorized.

Thus, authentication involves checking the validity of the user credentials, and authorization involves checking the rights and permissions over the resources that an authenticated user has.
