Instagram Cookie - How to use it during account creation

I searched the forum and couldn't find much info on this... what is the Instagram cookie, and how do we use it?

I'm assuming it's the cookie Instagram sent when an account was created and I should be able to find it in the browser? I know Jarvee has the ability to import a cookie, so then I would import it there? And what does that get me?

Web Cookies and different than API cookies. I wouldnt import Web Cookies into API / Automation, thats a "hack" and a red flag.

I'm asking because there is a seller of Instagram accounts that is providing the cookies with the accounts... just wondering why that is a bonus.

I prefer to create accounts myself but man, Instagram is fighting back so I am not able to do it fast enough.....

Cookies are a plus
He maybe add the accounts in jarvee then export it so you can import it to your jarvee with it's cookies
