During the winter break, you will continue to need to access your ASU account to enroll in courses, submit eForm requests to the ISSC, and for many other reasons. If you currently have the DUO authentication process set to send you a text or a call to your U.S. phone number, we would encourage you to change this, as many students do not have access to their U.S. phone numbers while outside the U.S. The ISSC cannot assist you while outside the U.S., if you are unable to access DUO.

1. Use the Duo mobile app on your phone or tablet (strongly recommended). 
   1. Log in at links.asu.edu/DuoDeviceManagement to activate your Duo mobile app before you leave the U.S. 
2. Use a Duo key fob (needs to be purchased before leaving the U.S.).
3. Use a hardware security key, like a YubiKey (needs to be purchased and set up before leaving the U.S.).
4. Use a platform authenticator (for example, Windows Hello, Chrome OS’s built-in security key, iCloud Keychain).

It is also recommended to enroll a second device to ensure you can always authenticate.
However, we strongly recommend using the Duo mobile app instead of text messages or voice calls. Using the app is much faster, it works anywhere you have an internet connection, and it’s much more secure than SMS messages or phone calls.

As a reminder, you must have whatever option you choose set up before you leave the U.S.
