Authentication

Authentication is the act of verifying a user's identity against a target system. Not to be confused with authorization, which simply verifies whether or not a user has the relevant privileges to access resources in a given system. Authentication in a web portal, for example, compares the username and password supplied by the user, with those held by the portal, in order to determine if that user has provided proper credentials for access. A hacker can sometimes recover these credentials through nefarious methods in order to spoof the system into giving them access as a trusted user.
