The website www.widget.com requires users to supply a username and a password. This information is encoded into a cookie and sent back to the browser. Whenever the user connects to the web server, the cookie is sent. This means that the user only needs to supply a password at the beginning of the session. Whenever the server requests reauthentication, the client simply sends the cookie. The name of the cookie is "identif." Assume that the password is kept in the clear in the cookie. What should the settings of the secure and expires fields be, and why? Assume that the name and password are hashed and that the hash is stored in the cookie. What information must the server store to determine the username associated with the cookie? Is the cookie storing state or acting as an authentication token, or both? Justify your answer.

Which of the following properties are true of "third-party cookies"? They are passed from a browser to any website that requests a list of all of a browser's stored cookies. They provide a mechanism for a website to track a browser's accesses to multiple other websites. Third-party cookies have a different format than first-party cookies that are issued by the website that a user explicitly chooses to visit by typing in the website's URL into a browser. They are explicitly mentioned in new privacy laws such as the EU General Data Protection Regulation (GDPR).
