Do I have to authenticate the second factor every day?
No. You can use the Trust Browser Function function in Duo. You will not be asked for a second factor for 14 days when you are on the computer using the browser you authenticated from.
Students, faculty, and staff can receive technical support any time—day or night, on weekends, and even holidays. If you need IT help, call 703-993-8870 anytime or submit a request ticket.
