How to use Two-Step login when outside the United States
This article applies to: Two-Step Login
You can use Two-Step Login when you travel internationally. All of the authentication methods will still work, although some destinations might not support telephony-based services: phone callbacks or retrieving a set of passcodes via SMS. Even if there is no cell or data service available for your smartphone or similar device, you can still use the Duo Mobile app to generate passcodes.
While in one of these embargoed countries, use a phone call or passcodes retrieved via SMS to authenticate with Two-Step Login.
