Web Users (= supervisors): They have access to CommCare Supply web where they can configure the CommCare Supply project settings and CommCare Supply web reports. You could have multiple web users managing mobile agents and viewing data outputs. After adding new web users, you could now set permissions to limit their data access. You could link a web user with a specific program/location, so that this web user can only see reports and data submitted by CommCare Supply mobile users associated with this program/location.
Mobile Users (= mobile workers): have access to CommCare Supply mobile application installed on their phone / tablet only. CommCare Supply mobile users can only be set up by a web user. You can manually create mobile users and associate each of them with specific locations and programs, or use the bulk upload tool to create mobile users and link them to programs/locations all in one go.
