Hi @btks,

If you use QuickBooks Desktop (QBDT) in offline mode, the system will never ask or require you to log in to your Intuit account. 

As for the other users in the thread asking if you can disable this feature, the answer is yes. I already shared an article in this thread, but in case you missed it, open this article: Intuit login is required every time a company file is opened. It has three different solutions you can apply to prevent the Intuit login prompt. 

I suggest you view this article as well: How to access QuickBooks Desktop files with One Intuit Account. You'll find a list of common questions about this feature, along with their answers. 

Post a question below if you have other concerns with the Intuit login prompt in QBDT. I'll be around to help you out.
