How does NodeBB Create it's sessions (and cookies)?

[UltraSabreman]

I'm trying to make it so my users can log into both my site and our nodebb forum with one account, but to do that I need to know how nodebb does it's sessions. I've been looking through the source but it's really confusing me.....
