IRS requires you to authenticate yourself via one of two mechanisms if you efile (regardless of who you do your taxes with):
1) Prior year AGI
2) Electronic filing PIN
They can also issue a taxpayer a special Identity Protection PIN. If you're issued one of these you MUST use it.
There are two groups of people that don't need to "authenticate" at all:
1) Anyone who didn't file the previous tax year
2) Anyone filing by mail
