Abstract: Certain aspects involve managing permissions in collaborative workspaces using visual representations of clients. For example, a graphical interface can be displayed that represents a collaborative workspace and that includes visual representations of different clients accessing the workspace. A workspace application executed by a processor can determine that visual representations for at least two clients are positioned in a common region of the graphical interface. The workspace application can authorize the clients to collaboratively modify electronic content that is accessible via the graphical interface based on the visual representations being positioned in the common region. Subsequently, the workspace application can determine that the visual representations are positioned outside the common region and restrict access to the collaboratively modified content accordingly.
