QODBC / QRemote or your application will not require QuickBooks credentials to connect to your QuickBooks company file.
When connecting using QODBC, QuickBooks will ask for “Application Integration Certificate / Permission. Only QuickBooks company file “Admin” can approve the connection. After approval, QuickBooks will save the approval information in the “Integrated Application” section.
Next time when the same application (for example, MS Access, MS Excel, Power BI) tries to connect using QODBC, QuickBooks will check the application that is trying to connect. QuickBooks will then validate the application based on the previous permission and will either allow or deny the connection.
