User authentication and cookies
User authentication (managing and handling user credentials) is another form of web security. In this section, we will use the user authentication feature available on the http://quotes.toscrape.com/login site, along with cookies.
As seen in Figure 6.6, http://quotes.toscrape.com/login contains a page with the Login text, and a form asking for Username and Password:

Analyzing the page source, there’s only a single <form> element found, with one hidden input element named csrf_token, two text input elements with type="text" (username and password), and finally, an object with the submit type and the value Login, as seen in Figure 6.7:
