Per call to ProSeries, there is a confirmed issue with two factor authentication.    For some reason, it has been turned off.   No pro-active communication that you need to go in to each user to setup again.

I asked if and why this hasn't been communicated and was instructed to blast this information through this forum.  

Only people who review this board will see this.  Why can't ProSeries be proactive when they know about issues.  Such a waste of time by users and the support team.
