I am setting up JWT authentication, everything is working fine but I got stuck at the last piece where I am not sure what I should do.

I have set up my Axios Config as this:

const token = ""

export const axios = Axios.create({
    baseURL: "http://localhost:8080",
    headers: {
        "Content-Type": "application/json",
        "Authorization": `Bearer ${token}`
      },
});

so here are few problems I have ..

1. if I want to log in, I need to have the "Auth" field to be gone, since I am not sending any cookie, if I do so, my backend fires an Exception since the cookie is not complete
2. How should I go about the Axios config, should I fill the "token" variable OR should I work here with the cookie in the local storage?
3. Is it a good practice to have multiple configs and use them simultaneously depending on the situation?

hope anyone can help me out! :)
