For the last two or so years, I start Fusion by double clicking on it’s icon (Windows box) and it starts up. Today’s experience was rather strange. Instead of fusion starting up, it asked me to sign in. After digging around for my login details and entering them, it then asked me to enter the one time pass code they sent. It then went to another window and promptly crashed the computer. After rebooting, it did start ok but it sure didn’t like my browser (Brave).  
I am wondering if anybody else has noticed the ‘new and improved’ two factor authorization.

I don’t know what happened to cause the hiccups but I have since started Fusion without having to go through two factor authentication. I did an update of Fusion just before the problems started so maybe it was related to that. In any case, things seem to be back to normal.
