If you are not traveling to a U.S. embargoed country, you can use Duo authentication when traveling internationally. This is true even without WiFi or cellular service. There are 2 preferred methods for getting passcodes:
- Use Duo Mobile while you travel
- Generate passcodes prior to travel
If you already own a hardware token or a U2F Security Key, you may also use those while traveling. If a staff or faculty member would like a hardware token mailed to them, IT will send it to their department. The department will be responsible for mailing the token to the user.
If you are traveling to a U.S. embargoed country, you may not use Duo. Read the Duo in embargoed countries disclaimer. For additional help, contact your supervisor, ITSS TechCenter Help Desk, or UMD's International Student Services.
