When traveling outside of the United States, the SMS and Call Me options within the Duo app may not work in certain countries. The following options are available for using Duo authentication:

Push notifications

If your mobile device is connected to the Internet and has the Duo mobile app installed, select the Send Me a Push button to send a push notification to the Duo app on your mobile device.

Token generator

If you do not have a smartphone, you can request a token generator, which generates a passcode. It does not require an internet connection and is small enough to put on a keychain. Contact IT to request a physical token.

Bypass code

If you reach out to IT in advance, we can generate a multiple-use security code that will be valid for the duration of your travels. This code should be securely stored on your person (e.g., in a wallet).
