Recently I have been replacing my 2 prong outlets with 3 prong. I found out it is dangerous to have an open ground 3 prong. To update this to code I am wondering if it is ok to put a gfci in the most upstream receptacle of the circuit, so the ungrounded 3 prongs will be up to code and safer,
I am also wondering if the ungrounded 3 prongs that are on the gfci circuit need to be tamper resistant?
My county uses the 2014 NEC code.
Any help would be greatly appreciated.

As of 2014 the NEC requires tamper resistant outlets. You are correct about how to install a GFCI at the head of a circuit and replace the old receptacles with new three pronged receptacles, But the NEC requires that the receptacles be labeled as “No Equipment Ground” . When you purchase the GFCI's those labels should be in the box with the GFCI's.
