* Since Inforiver is an add-on visual that operates on top of the Power BI framework, users must log in with their Microsoft O365 account. [Admin consent](/introduction-to-inforiver/get-started/inforiver-writeback-matrix-prerequisites/admin-consent-for-inforivers-entra-id.md) will be required to log in, add writeback destinations, or connect to integrations like Teams or SharePoint.
