Others Java New Game Manager/Thread Formatting

I will finish the basic features and then upload the jar.
I can´t host it myself for now as I can´t cover the expenses, but anyone can run it locally or host it somewhere on a free account just for themselves.

Another question.
I am currently working on anything related to authentication in the API (login, register, restore...).
Most things on this website require a user to be logged in to access something, so I get and use the users cookies to achieve that.
I am not too familiar with how cookies work exavtly, but I found several cookies and was wondering what each is used for.

"xf_session": "",
"xf_csrf": "",
"xf_user": "",
"_ga": "",
"__ddg1_": "",
"_ga_HE9XJLVKML": "",
"d_uid": "",
"d_uidb": "",
"_gat_gtag_UA_67186250_3": "",
"_gid": ""

From my testing, "xf_user" and "xf_csrf" can each be used to identify a user and i know some are for google analytics, but what about the rest? Anything important?
