Duo Two-factor Authentication
Duo: Account Management
Duo / Check the Rate Card for international travel
Duo / Check the Rate Card for international travel
Objective
To provide access to the Duo Rate Card to discover or verify credit charges for use during international travel
To provide information about offline Duo authentication options for use during international travel
Scope
Duo provides offline authentication options for times when you are without cell service or traveling internationally
The passcode option on the Duo Mobile app does not require wireless or cellular connectivity; and it can be used in airplane mode
Environment
312306: Duo Security Two-factor Authentication
Cause
When traveling outside of the continental United States, authentication via SMS text may not work, because Duo's rate charges exceed the limit of 20 credits
Resolution
Before traveling internationally
,
check the Duo Rate Card
to see if the rate charge for a single SMS text message is less than 20 credits
Duo will not send an SMS text message, if a single SMS text message uses more than 20 credits
If the location credit rate
exceeds
20 credits,
then use the preferred offline authentication method
: the option to generate a passcode in the Duo Mobile app on your device
Open the Duo Mobile app on your device and generate a single-use passcode within the app
Enter the code provided in the passcode field of the Duo authentication prompt
If you use a different phone when in your home country and don't have a data or cellular plan with your U.S. smartphone:
Duo / Enroll your international device as a secondary device
If you don't have Duo Mobile installed on a device:
Learn how to buy a YubiKey hardware token
and
enroll your YubiKey for use with Duo
before departing for international travel
Use a YubiKey hardware token to authenticate through Duo
If you do not have access to any of the options listed, contact IT Help by phone at
