Authentication and authorisation are often thought of as a single process but the two are actually distinct operations that may even use separate storage locations for the authentication and authorisation data.

Kerberos authentication explained | markwilson.it

Authentication is about verifying identity, based on one or more factors, for example something that someone knows (e.g. a password), something that someone holds (e.g. a smart card), something that someone is (e.g. biometric information). Obviously the use of multiple-factor identification increases security. Authorisation is about controlling access to a resource based on access control lists and other policies; however secure authorisation is dependant on authentication in order to ensure that the security principle requesting access is who they say they are.
