I am just as frustrated with everyone else about this but I think I may have somewhat solved the problem. (Although QuickBooks should solve the problem for everyone with what I am sure is a simple programming change.) I have two companies that I constantly have to log in and out of. I used the Firefox browser and so far I have been able to go back and forth between the two without entering a texted code. I don't know how long I can go without it but this is at least an improvement for now. I am putting this here in case someone else can be helped just a little by this.
