It’s up to the user to know and understand the implications of using his/her cell service while abroad (cost to use the phone abroad, cellular service availability where traveling, etc.). If the user is satisfied with those conditions and is planning to use his/her device normally while traveling, then using the device as the second-factor will not change. If using a smartphone, then an enrolled user can simply use the Duo Mobile app to generate a passcode each time authentication is needed regardless of the implications of using a cellular service abroad or whether there is any Internet connectivity. See how to generate a passcode
on your mobile smartphone or tablet.
For those who will not be able to use their mobile devices while traveling, another option is the purchase of a Duo hardware token before leaving. Duo Tokens are available upon request. Allow enough time for the purchase to be completed and the Duo Token to be delivered to ensure that the token is available when needed. Contact your ITS building technician
or the ITS Helpdesk
