Shared Computer Activation (SCA) is a product activation mode that allows multiple Office 365 ProPlus, Project for Office 365, and Visio Pro for Office 365 users to share the same hardware. Office 365 is licensed per user, so SCA helps ensure that users accessing Office 365 ProPlus, Project for Office 365, and Visio Pro for Office 365 are licensed appropriately.
