CAESAR and Multi-factor Authentication

As you prepare for your study abroad experience, please note that Multi-Factor Authentication (MFA) remains active on CAESAR and you will continue to need a phone (either a smartphone, cell phone or landline) to verify your identity when logging in from abroad. The IT Support Center recommends that you register your phone with the Duo Mobile app. Instructions for setting up Duo Mobile are availabe in the IT Knowledge Base.

If you know the international phone number that you’ll use while abroad, it is strongly recommended that you add that number to your Duo account before you leave the U.S.

If you only have a U.S phone number registered and that phone won’t be available to you while traveling or you won’t have an international number until you arrive onsite, you will need to email the IT Support Office after an international phone and number have been established. The email should be sent to consultant@northwestern.edu and include:

  • A scanned copy of a current, valid photo ID (e.g., passport or Wildcard) in order to confirm your identity, and
  • The U.S. phone number you wish to have removed from your registration.

Your U.S. phone number will be removed from your registration by a MFA administrator. Once your receive a confirmation via email, you may register your international phone number. Note: If you would prefer to call the IT Support Center at 847-491-4357 (1-HELP), please call during regular business hours Monday through Friday, 7:30 a.m. to 5:00 p.m. CST.

If you have any questions, please review the MFA Frequently Asked Questions and the MFA Quick Guide.
