Greetings from the International Students and Scholars Center. We hope you are doing well and staying healthy.

ASU is committed to protecting students from fraud and scams that attempt to steal personal and financial information. ASU uses two-factor authentication to protect you and your data from cybersecurity threats. Enabling two-factor authentication on webpages that display personal and banking information is an essential means to protect student data

As many students may not have access to their U.S. phone number while outside the U.S., here are your options to ensure you have access to your ASU account while abroad:

  1. Use the Duo mobile app on your phone or tablet (strongly recommended).
  2. Use a Duo key fob (purchase at 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. 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.
