What is the primary function of entity authentication?

The primary function of entity authentication is to ensure a user is who they claim to be. This process verifies the identity of individuals attempting to access a system, application, or data. It typically involves mechanisms such as passwords, biometric data, security tokens, or multi-factor authentication. This is crucial in maintaining the security and integrity of sensitive information and systems, as authenticating users effectively prevents unauthorized access. By confirming a user's identity, organizations can safeguard their resources against potential breaches and ensure that only those with the appropriate credentials can access certain data or perform specific actions.
