Before You Travel
Decide which devices to use
When deciding which devices to use for travel keep in mind that certain multi-factor options only work with certain connection options.
Device options
-
Use your current phone with an international cell plan that can receive calls/texts.
-
Use your current phone but switch SIM cards for your international plan.
-
Get a new phone abroad [Requires most planning]
-
Use a wifi enabled device [i.e. phone or tablet]
You should set up your tablet on WiFi with the Duo Mobile App before you leave, then while abroad, you would need WiFi and use Duo Push or use the Mobile App passcodes.

Decide what multi-factor authentication methods to use
While traveling, you may need to use different multi-factor options depending on the cellular or wifi availability.
Set up your devices
Once you’ve decided which devices and multi-factor methods to use during travel it is time to set your devices.
Make sure you set up your device prior to travel. We recommend you set up multiple devices and multi-factor options to have as a backup.
Minimum Recommendations
Download and Activate the Duo Mobile app
The Duo mobile app is the most effective tool for using multi-factor authentication during travel.
The Duo Mobile application can be used to generate passcodes on airplanes or in remote regions where Duo Push, SMS-delivered passcodes, or phone callback may be unavailable or difficult to use due to lack of Internet or cellular service.
The app can also send Duo Push notifications when wifi or an Internet connection are available to your authentication device. If you can access the Internet from your mobile device, you can receive push notifications.
Generate SMS Backup Passcodes
Before you leave, you can use your existing Duo setup to send yourself a text message with ten backup codes. The passcodes are one-time use (cross them out as you use them). All ten codes expire after 14 days. Use these codes to access Duo-protected systems before setting up your new device. Keep in mind that if you create a set of backup codes and then create a second set later, the first set will expire.
We strongly advise you to obtain a new set of backup passcodes every 14 days. Set a reminder on your phone or calendar to ensure that you remember to do this. Generate your first set of codes before leaving the United States.
Backup passcode tips
Additional Options
Set up a Security Key
If you have a Security Key, please make sure you set it up prior to travel.
Set up Phone for Phone Calls
While this is an option for authentication, we highly recommend against using the phone call method as a multi-factor authentication alternative as it is highly unreliable, particularly in travel settings.
If you do decide to use phone calls as an authentication method, please ensure that you have a backup plan using one of the minimum recommendations above.
Things to keep in mind:
-
Use your current phone but switch SIM cards for your international plan.
Switching SIM cards will change the phone number you are using for your device. In order to set this up properly you will need to make sure that you are using the Duo Mobile App and not relying on SMS-only setup as the SMS codes will be sent to your domestic number unless it is updated.
Prior to travel provide IT Central with information about the international phone number associated with the new international SIM card so it can be manually registered to your multi-factor profile. Then when you're in your destination country, reactivate your phone using Duo Mobile.
-
Get a new phone abroad [Requires most planning]
-
If this is the option you are choosing, ensure that a secondary multi-factor option is set up prior to travel. We recommend using either the Duo mobile app set up on your regular smartphone or tablet with wifi enabled capabilities or send yourself backup passcodes no more than 2 days prior to travel to have available for when you are setting up your new phone. You should then purchase the new phone within 14 days of arriving at your destination and use either the device with Duo Mobile activated or one of the backup codes to set up the new device with multi-factor.
