| **User Authentication** verifies the identity of a user attempting to gain access to a network or computing resource by authorizing a human-to-machine transfer of credentials during interactions on a network to confirm a user's authenticity. The term contrasts with [[dido:public:ra:xapend:xapend.a_glossary:m:machine_authentication]], which is an automated authentication method that does not require user input. | **User Authentication** verifies the identity of a user attempting to gain access to a network or computing resource by authorizing a human-to-machine transfer of credentials during interactions on a network to confirm a user's authenticity.

Almost all human-to-computer interactions -- other than guest and automatically logged-in accounts -- perform user authentication. It authorizes access on both wired and wireless networks to enable access to networked and internet-connected systems and resources. | + | [[dido:public:ra:xapend:xapend.a_glossary:a:authentication]] helps ensure only authorized users can gain access to a system by preventing unauthorized users from gaining access and potentially damaging systems, stealing information, or causing other problems.
