Hi ChristineJoieR

Unfortunately, that answer doesn't address the problem that QB 2019 requires verification of my Intuit account every few months - and that is done through the QB IE browser in a pop-up window.

Here's what I wrote to your colleague. 

Although QB 2019 doesn't require Internet Explorer to login every time I open quickbooks - it DOES every couple of months want me to verify my Intuit account or it won't let me login.

And that Verification does take me to a browser and require me to login to my main Intuit Account. So what happens when IE 11 no longer works - I won't be able to use quickbooks 2019 because I can't verify my Intuit account in the browser.
