Faculty/staff and students who are traveling outside of the U.S. have options for using Duo.
If you will have your mobile device:
The Duo app will generate passcodes even if your mobile device is not connected to wifi or a cellular network
Beginning in March 2019, China (Mainland/People’s Republic of China) put into place regulations that affect phone callback authentication deliverability. Due to these regulations, phone call authentication can be considered an unreliable authentication method to use for China-based Duo users attempting to call their devices. The Duo App should be used. See this link for more information on using Duo Mobile in China.
If you will NOT have your mobile device (for faculty/staff):
Use a FOB - see this FAQ for more information
The Duo Mobile app and Duo fob are subject to Export Control Regulations, contain controlled cryptographic technology, and may not be taken to U.S. embargoed countries such as Cuba, Iran, North Korea, Syria, Sudan, the Crimea region of Ukraine. Before traveling to any U.S. embargoed countries, you must delete the Duo Mobile app from any devices you will take with you and you must not bring a Duo fob. While traveling, you may use other Duo options described in this FAQ, such as a phone call or passcodes.
If traveling outside of the U.S. with University owned Duo fobs, please complete the Checklist for International Travel with University-Owned Equipment prior to traveling. Please contact the University Export Control Officer (firstname.lastname@example.org) before traveling to an embargoed country.
