Check the authentication rate card for international travel / Duo

Body

I need to access the Duo Rate Card to verify credit charges for authentication during international travel
What are my offline Duo authentication options for use during international travel?

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
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

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
1. Open the Duo Mobile app on your device and generate a single-use passcode within the app
2. 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 hardware token and enroll your token for use with Duo before departing for international travel
- Use a hardware token to authenticate through Duo
If you do not have access to any of the options listed, contact IT Help by phone at 513-529-7900 or by live chat at MiamiOH.edu/ITChat for assistance

All current Miami University Students, Faculty, and Staff, plus Alumni, Retirees, and Emeriti are required to enroll in Duo
