What is one significant role of access groups in Pega?

Access groups in Pega play a critical role in identifying the application for user login because they define the set of permissions and access rights that a user has within the Pega platform. When a user logs into the system, the access group determines which application the user is associated with, allowing the system to tailor the user experience according to the specific roles and responsibilities assigned to that group. This functionality is essential for ensuring that users can effectively interact with the elements of the application relevant to their job functions while maintaining the security and integrity of the application environment.

Access groups also provide the mechanism for linking users to specific rules and data based on their organizational role, which is foundational for Pega's role-based access security model. Thus, by identifying the application for user login, access groups facilitate access control, user management, and overall application governance.
