This document explains how to log out of NetID Login Service.
How To Log Out
You must exit your browser (Quit on a Mac) to log out of your NetID Login session and make sure your session cookies are cleared (see Clearing Browser Cache and Cookies).
Making sure your browser doesn't save your NetID session

Depending on the browser's settings and version, it's possible that the Logout Procedure above will not clear your NetID Login session.
