DUO - Delete a Device From Duo

Context: 

Device management in DUO allows you to delete a registered device if it is lost or stolen. Before you delete a device, make sure there is at least one other device added (a regular phone, tablet, or a temporary bypass code from the CMC Help Desk) or else you will not be able to sign in using DUO.

Contact the CMC Help Desk for further assistance if you are not able to access your account.
