Expect to need to authenticate when signing in at least once per day. Sometimes more often, depending on how you work, what systems you use, what kind of device you use to access those services, and how often you change your location, e.g. from your workplace to a classroom, to home or some other place.
If you have an ORU computer and are on campus, you will have fewer authentication requirements than if you work elsewhere.
In addition, Office apps require re-authentication with regularity, both on desktop and mobile devices.
IT Services is working to improve the user experience with as few authentication requests as necessary.
