DUO Restrictions Starting May 5, 2022


DUO will begin restrictions in some areas of the globe as tensions rise between nations. DUO will be unavailable in these regions. To comply with U.S. regulations, DUO will begin blocking authentications from users whose IP address originates in a country or region subject to economic and trade sanctions enforced by the U.S. Office of Foreign Assets Control.

Beginning May 5, 2022, users attempting to authenticate to a DUO-protected application from an access device with an IP address originating in an OFAC-regulated country or region will be blocked from completing their login and receive an error message.

Web-based applications will display the following error message: “Access denied. Duo Security does not provide services in your current location.” Other applications may display a generic failed login message.
