What is the first entrance to the airport called? [closed]

I am looking to know the terminology. I will start with the sequence in reverse so everybody understands what I'm trying to figure out -

Gate - This is where you are finally checked along with your boarding pass and passport before either a bus ferries you to the plane or you go on to the bridge to the plane.
Check-in-counter - This is where you get your boarding pass and are told which gate or terminal your flight will start from and how you should navigate.
Security - This is where your bags are checked to see if you are not carrying any illegal substances.
First gate - (the one I'm enquiring about) - This is where your printed ticket along with your passport is checked and matched with your face for the first time.

Look forward to know what is it called ?
