This guide is provided by Conductor, the service that powers the QuickBooks Desktop integration for many business tools, including the one that sent you here.
When you first add a Web Connector connection, QuickBooks Desktop shows an Application Certificate window. In that window you choose important permissions for the connection – for example whether the application can connect when QuickBooks is closed, which user it should log in as, and whether it can access sensitive information. This guide explains how to open that same configuration view again so you can change any preference for an existing Web Connector connection.

Change the desired settings

The connection Properties window is the same window you saw when you intiially added the Web Connector connection. Here you can adjust:
  1. Access rights – for unattended syncing we recommend selecting “Yes, always; allow access even when QuickBooks is not running”.
  2. Login as – choose which QuickBooks user the connection will use. (See Change the QuickBooks Desktop user for a connection for more details.)
  3. Personal data access – check or un-check “Allow this application to access personal data such as Social Security Numbers and customer credit card information” depending on your needs.
  4. Any other options provided by QuickBooks Desktop or your specific QuickBooks version.
