Solution

Duo to block authentications in countries or regions subject to OFAC sanctions

As of May 5, 2022, the University's 2-factor 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). 
 VCU Affiliates attempting to authenticate to 2Factor Duo-protected applications from the following OFAC-regulated countries or regions will be blocked from completing their login. They will receive an error message: "Access denied. DUO Security does not provide services in your current location."

  • Cuba
  • North Korea
  • Iran
  • Sudan
  • Syria
  • Crimea region
  • Sevastopol region
  • Donetsk region
  • Luhansk region

This means that VCU affiliates based in or traveling to these countries or regions cannot access VCU's services (such as RAMS VPN, Gmail, Canvas, eServices, etc.) that require DUO authentication.

Additional Information

Note:  China is not on the list, but China, itself, may block the usage of Duo.  If you are planning a trip to China, it is recommended that you bring a hardware token to use.
