csrf_token what is it

I am trying to make my own login form, but when I look at other peoples login forms, or the dolphin login form I see a csrf_token like this.... value="Tg3Sktxqc7txg+VGXD=Q"

So what is this? I looked on this forum but the written info is basicaly  too complex and I have no idea what the heck its going on about. 

When I make my login from is there a csrf token I need to put in? if so where do i get it from? does it generate automatically when people come to my site?

in other words what do I put in this value field?

<input type="hidden" value="WHAT THE FRICK DO I PUT HERE???" name="csrf_token" class="form_input_hidden">
