The purpose of authentication in cybersecurity is to confirm users’ identities. Authentication is a fundamental security process that verifies whether a user, system, or entity is who they claim to be. This is often achieved through mechanisms such as passwords, biometrics, or security tokens. By confirming identities, organizations can ensure that only authorized individuals gain access to systems and data, thereby reducing the risk of unauthorized access and potential security breaches.

Authentication is vital for maintaining a secure environment because it lays the groundwork for other security measures, such as authorization and auditing. Without proper authentication, it would be challenging to implement effective access controls or to track user activities within a system. Thus, the main objective of authentication is to create a reliable mechanism for identifying users and differentiating between legitimate and unauthorized access attempts.
