What is the primary purpose of "Session Management" in Salesforce?

Session Management in Salesforce primarily focuses on monitoring user sessions and managing active sessions to ensure security within the platform. This aspect is crucial because it helps administrators track when and where users are accessing their accounts, which is vital for maintaining the integrity of the system and protecting sensitive data.

By managing active sessions, Salesforce can enforce policies such as session timeouts, allowing for automatic logging out of users after a period of inactivity. This minimizes the risk of unauthorized access if a user leaves their session open in a public or shared environment. Additionally, it helps in identifying and responding to potential security threats by providing visibility into user activity.

The other options, while related to different aspects of Salesforce, do not align with the core objective of Session Management. User training on system updates, enhancing user interface design, and enabling mobile access are all important functions, but they do not pertain specifically to the security and active oversight of user sessions that define the purpose of Session Management in Salesforce.
