If you are a Duo Security user and you have setup a telephone, you must be able to physically reach the telephone. When Duo Security contacts your telephone, you must touch the phone – answer it, press buttons – to authenticate. If you can’t reach the phone, you will not be able to authenticate.
For additional information or assistance, please contact the Tech Desk at 570.577.7777 or firstname.lastname@example.org.
