Duo and International Travel

If you travel internationally, don’t worry – Duo authentication can work without cellular service or a wifi connection.

Users have several options that may be useful:

  1. Smartphone/Tablet – Even with cellular service disabled or without a wifi connection, you may use the Duo Mobile app to generate a passcode that you can use to authentication. Simply choose the Enter a Passcode option when you get the Duo authentication prompt. To generate the passcode, open the Duo Mobile app on your phone or tablet and tap the button with the KEY symbol.
  2. Hardware token – if you don’t have a smartphone/tablet and you travel internationally often, you may want to get a hardware token (contact the Service Desk to start the process). Simply choose the Enter a Passcode option when you get the Duo authentication prompt and then enter the passcode that shows on the hardware token. Note: there is a one-time $45 fee for hardware tokens.
  3. ByPass Code – If you won’t have a smartphone/tablet and a hardware token is not an option, it is possible to get a bypass code that you can use for Duo authentication for the duration of your trip. Contact the Service Desk to request this option. Then, simply choose the Enter a Passcode option when you get the Duo authentication prompt and enter the bypass code that you were given.
  4. Normal options – If you have cellular service or a wifi connection, then you can simply use whatever authentication technique you normally use. The push, passcode, and phone options all work overseas. You can even add an international phone number as one of your authentication options.

If you have questions about any of these authentication options, please consult the Duo FAQ page or the Duo User Guide.
