Beginning May 5, 2022, the University’s two-step verification tool, 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 (OFAC). Harvard affiliates attempting to authenticate to HarvardKey- and Duo-protected applications from the following OFAC-regulated countries or regions will be blocked from completing their login and will receive an error message:
- North Korea
- Crimea region
- Sevastopol region
- Donetsk region
- Luhansk region
This means that Harvard affiliates based in or traveling to these countries or regions will not be able to access or communicate via most University-provided technology resources.
Due to University security requirements, there are no recommended alternatives to HarvardKey-protected applications.
Please contact the IT Helpdesk at (617) 432-4357 or email firstname.lastname@example.org for any questions or concerns you may have regarding this information.
