I had the opposite problem and tried to login to QBO after turning off my computer. I never got the email code to login and it said I had to contact Intuit. After waiting 15 min for the support to find the answer why email wasn't working I gave up. I have work to get done and can't sit on hold all day. He came back and said he didn't know how to fix but by then I had already logged into another browser using my phone number. Its such a waste of time to call support but it does worry me we could easily be locked out of the software which isn't good at a deadline.
