Many applications use “inactivity time-outs” as a security measure to prevent unauthorized access; they do this by closing any session when no activity has occurred within that application for a certain period of time. Most of the myHumboldt applications time out after 45 minutes of inactivity; Moodle, STARS, and the Library Articles & Databases applications time out after two hours, and Gmail and other Google Apps, which can run for one to three days of inactivity before timing out.
