Clear user session on closing browser in Wordpress

Question

I want to clear the current session of a user on frontend in wordpress while closing the browser or tab. Currently when I login and close the browser, the user is already logged in.

I am using Wordpress 4.0 version. So please advise how I achieve this.

Answer 1

If you can include a JavaScript and know the exact wordpress cookie you can use following code to detect on close event and inside clear the cookie

window.onbeforeunload = function () {
       // Clear cookie here
      };

Answer 2

Why don't you use the wp_logout function? Destroys the active session.
