Travel to OFAC-Sanctioned Countries
To comply with regulations and sanctions enforced by the U.S. Office of Foreign Assets Control, services such as Microsoft Office 365, GlobalProtect, Zoom, and Duo block authentication requests whose IP address originates in a country or region subject to economic and trade sanctions. These regions are updated from time to time but presently include:
- Cuba
- North Korea
- Iran
- Sudan
- Syria
- Crimea region
- Sevastopol region
- Donetsk region
- Luhansk region
This restriction applies to all Duo Authentication methods, including the Duo mobile app, hardware tokens, SMS text message codes, and phone calls. In order to comply with security best practices and due to Duo's legal obligations, there are currently no recommended workarounds for this restriction. Anyone traveling to the above countries/regions should note that Villanova services protected by Duo will not be accessible from these locations.
Duo offers multiple options to meet your needs when traveling. You may be able to use the Duo two-factor authentication option already installed on your phone to log in to two-factor protected systems while traveling. Depending on your travel plans, however, you may prefer to use a better-suited, alternative option.
Before your trip, determine which Duo options will best meet your needs and, if necessary, enroll your devices. See How to Travel With Duo for descriptions of the options that are best for different travel scenarios.
Consider using Passcodes
If you will not have access to your phone, or will be without reliable cellular service or a WiFi connection while traveling, plan to use passcodes.

Duo Push
If you do have cellular service or a WiFi connection, simply use whatever authentication technique you normally use. Duo push is recommended as the primary option. You may also use the Duo Passcode, text message or phone call that all work overseas if your cell phone carrier plan supports international text messages and phone calls. You can even add an international phone number as one of your authentication options.

Duo Passcode
When cellular service is disabled or you have no WiFi connection, you may use the Duo Mobile app to generate a passcode for authentication. Simply choose the Enter a Passcode option when you get the Duo authentication prompt. To generate the passcode, open the Duo Mobile app on your phone and tap "show" to display the passcode.

Text Message
While a cell phone connection is required, text messages can often still be transmitted through spotty data coverage. If you choose this option, Duo will send a set of 10 single-use passcodes in one text message. These passcodes remain active for up to 30 days.

Add a Device for Traveling
If you purchase a phone for use abroad, it is highly recommended that you enroll that device in Duo and use it for two-factor authentication while traveling.
- Enroll the device ahead of time. To enroll your new device, you'll be required to use the Duo authentication method already associated with your account, so it is best to do that before your trip if at all possible. Once enrolled, you can update the preferred authentication method for your new device.
- Use what works. If you plan to travel with a basic, non-smart phone, you can authenticate using a phone call or passcodes sent via text message. Alternatively, you can install the Duo Mobile app on a tablet without a phone number.
Please work with your individual wireless carrier to ensure all travel plans are in place before going abroad.
