Hi there, Prajapati.

I recognize turning off the Integrated Applications isn't the best way to resolve your issue since Web Connector is critical for your workflow. Let me provide you with another troubleshooting option to overcome the pop-up issue.

QuickBooks Desktop will base on the setup of your Windows settings. In this case, you'll need to check the universal settings of the browser to verify if it deletes cache or cookies automatically. Thus, this may cause a login pop-up upon running Web Connector in QuickBooks.

If you're not sure how to check the universal settings, I recommend seeking help from an IT professional.

Just in case you encounter specific errors when running Web Connector, you can check out this article to learn how to fix it: Fix common Web Connector errors in QuickBooks Desktop.

Come back to this post if you have other concerns or follow-up questions about this. I'll be around to provide further assistance.
