Yes, it is frustrating that Intuit has chosen not to address this issue other than to try to drive folks to the online subscription model, but there are a few solutions that creative readers of this thread have uncovered.  One is sure to help you but you will need to dig into this long thread  to find what will work best for you.  I personally use the firewall  fix - blocking just the Quickbooks program from accessing the internet, then it stops asking you to log in.  Other fixes abound that seem to work for some folks but not others.  Find what works for you.
