We bought a new computer and I set up QB with an icon.  Didn’t have to have the code sent to me.  However, we had 2 web browsers on the computer.  Firefox and I think Edge.  My husband deleted Edge because he didn’t like it and now we are back to having to get the code sent to my phone.  So maybe try another browser.  I haven’t had a chance to mess with it to figure out if it will work for us but will in the next day or two.
