How can you check the effective permissions of an account in Sitecore?

The Access Viewer is a tool specifically designed to help administrators and developers in Sitecore to visualize the permissions assigned to individual accounts or roles. When using the Access Viewer, you can see the effective permissions, which means it will display the permissions that are currently applied, taking into account all role memberships and specific access rights. This tool helps to streamline the process of determining what an account can access at a granular level across the Sitecore content tree.

While other options may provide useful information about managing users and permissions, they do not specifically focus on the effective permissions aspect. For instance, the Permission Checker enables you to check permissions but is less visual and user-friendly for this task compared to the Access Viewer. The User Management panel is primarily for managing users and roles rather than directly assessing permissions. System logging logs various events but does not provide a direct interface for reviewing effective permissions. Thus, the Access Viewer is the most appropriate choice for understanding the effective permissions of an account in Sitecore.
