A cookie is basically just an item in a dictionary. Each item has a key and a value. For authentication, the key could be something like 'username' and the value would be the username. Each time you make a request to a website, your browser will include the cookies in the request, and the host server will check the cookies. So authentication can be done automatically like that. To set a cookie, you just have to add it to the response the server sends back after requests. The browser will then add the cookie upon receiving the response. https://stackoverflow.com/questions/17769011/how-does-cookie-based-authentication-work https://stackoverflow.com/questions/17769011/how-does-cookie...
