Sending requests with User Id to router using Node.js?

Question

Computer networks

It all started when I dug up my old Asus router.
Having done all the manipulations, I went to the web interface, but after five minutes my eyes were dripping. Spread out over ten pages with a full load and all that.
Naturally, I wanted to write a simple grabber, so as not to ruin my eyes and brains. (No need to write about similar bikes, I want my own)
But then, naturally, the problem of authorization arose. Judging by what he gives, "some" user id is needed. Google didn't help unfortunately.
As for the question, I think it is already clear. I’ll clarify right away that it will be interesting to find out if there are packages for working with this user id, or, more precisely, with this type of authorization. For reference (or just idle curiosity), I will say that I used the request package for requests and the cheerio package for parsing.
