What must be done to remove a user from an administrator role in Sitecore?

To remove a user from an administrator role in Sitecore, the action of removing the user or deleting their administrator role is essential. When a user is assigned to the administrator role, they possess certain privileges and access within the Sitecore platform that allows them to perform administrative tasks. To ensure that the user no longer has these elevated permissions, it is necessary to either remove the user entirely from that specific role or to delete the role itself.

This process guarantees that the user does not retain any administrative capabilities, which is vital for maintaining proper security protocols and ensuring that only designated individuals have control over sensitive functions within Sitecore. The focus on either action emphasizes the importance of precise role management in a system where user access and permissions play a crucial role in overall governance and security.

Other options, such as degrading privileges or reassigning to a different role, do not directly address the need to specifically remove the user from the administrative role. While notifying the user can be a consideration for communication purposes, it is not a requirement for the technical action of modifying role assignments in Sitecore.
