How to Delete Browser Cookies

Our online courses use cookies to determine when you are logged in. In principle, when you close a browser or shut off your computer, these login cookies should be removed. Periodically this does not work as intended, perhaps due to the use of multiple tabs and multiple browsers for the same course session.

In any event, if you get notice that you cannot enter a page because you are already logged in, then this is likely an issue with these login cookies. The easy way to avoid this is to log out when done with a course session before closing the browser or before just leaving your browser open to move on to other computer projects.

After you delete your cookies, then you can login and then logout and that should put you back to normal.

There are two ways to remove cookies from your browser. One is more of a shotgun, deleting all cookies from all sites in the browser;  the other method deletes cookies from just a specific website, leaving others undisturbed.
