I seem to remember somewhere that disabling the Payroll feature would stop the need to "login".

As I only have one other person who works part time as contract labor, I do not use the Payroll feature. I disabled it.  I made my back-up and closed QB Premier 2019 as I always do.  Upon re-opening QB there was a bit of a delay before the software package opened.  For a few minutes I was worried it might not load/start.

It did, and I have not seen the requirement to "login to my Intuit Account" online since.
