What is a primary goal for organizations using user identity authentication?

User identity authentication is primarily aimed at safeguarding sensitive information from unauthorized access. This process verifies the identity of users seeking to access a network or system, ensuring that only authorized personnel can view or handle confidential data. By implementing strong authentication measures, organizations create a secure environment where sensitive information—like personal data, financial records, and proprietary business information—is protected from malicious actors and inadvertent disclosures.

The other options do not align with the fundamental purpose of user identity authentication. Providing unlimited access to all network users contradicts the idea of security and protection since unrestricted access would open vulnerabilities. Monitoring employee productivity, while potentially beneficial for overall organizational management, is not the primary concern of user identity verification. Increasing the number of network devices does not directly relate to identity authentication, which focuses instead on who can access the existing devices and information within the network.
