Yes, but the benefit of this 2-step was to extend the time-out to much longer period.  I found the Inuit notice: 

With current IRS security requirements your tax software login timeout occurs after 30 minutes of inactivity, however the IRS is extending this to 12 hours starting sometime in January. This change is due to the expectation that Tax Pros will have adopted two step verification to make their software login more secure. 

ProSeries will extend the login timeout in February. 

When, February 29?
