Duo Multi-Factor Authentication (MFA)

how duo works

DUO multi-factor authentication (MFA) is an additional method of verifying your identity and protecting your information when you log into  CSUSM systems and websites. 

All students, staff, and faculty accessing CSUSM systems and application are required to use multi-factor authentication.

  • Where do I go to install the app on my smart device?
  • Do I need a mobile phone to use Duo?

    Although a mobile smartphone is the easiest and most convenient way to use DUO, you may also connect the Duo Mobile application using a tablet. If you have no smartphone or tablet, your smartphone is too old (iOS 10 and older or Android 5 and older), or you would prefer not to use your personal smartphone with the Duo Mobile app, you may request a hardware token (key fob) to use instead.  Please make arrangements to go to the helpdesk to request a key fob.  Make sure to bring your campus ID when you come to pick it up.

  • What happens if I lose or forget my Duo connected device or fob?

    If you lose your phone or suspect it has been stolen, contact the helpdesk immediately. The team can disable your phone from being able to authenticate with multi-factor authentication and can assist you with logging in with another method.

  • How do I allow Duo on my browser to remember me for 24 hours?

    To avoid being prompted by Duo multiple times a day, select the checkbox next to Remember Me for 24 hours during log-in.

    Due to some technical limitations on Remember Me for 24 hours:

    • It won’t carry over between different websites, computers, or when switching between web browsers (from Chrome to Firefox, for example).

    • It may not carry over between different internet providers, campus services, if you block cookies, or are using Incognito mode.

  • What if I cannot scan the QR code?

    If you are unable to scan the QR code for any reason, there is alternative way by sending a code to your CSUSM email:

    1. When you are prompted in the CSUSM app, click "Take me to Duo mobile"

  • I plan on traveling outside of the United States

    Duo restricts authentications to any country or region whose IP address "originates in a country or region subject to economic and trade sanctions enforced by the U.S. Office of Foreign Assets Control."

    Duo maintains a list of regions and country codes that are currently restricted and updates it regularly.

    Please review this list before traveling outside the United States, and if you are visiting a sanctioned country or region:

    • You MUST uninstall DUO from any device that has DUO installed
    • DO NOT take your DUO hardware token with you.

    Traveling With DUO to non-sanctioned countries
    Options: Most of the time, you can safely use the DUO mobile app on a smartphone or tablet. Even if you don’t have cell phone service or a Wi-Fi connection, the app can still generate a passcode. If possible, enroll a secondary device in case your primary device is unavailable. (NOTE: try to avoid taking your device(s) to a high risk country).
    Hardware Token: If you are traveling without a smartphone or tablet, take your hardware token with you (unless you are traveling to a sanctioned country).
