Duo multi-factor authentication is required for all LMU and LLS accounts, including students, faculty, and staff. All new accounts will be automatically enrolled, and will receive a registration email from Duo with sign-up instructions. The implementation of Duo has greatly reduced the number of compromised LMU and LLS accounts.

What Is Duo

Duo multi-factor authentication provides additional security for LMU systems by requiring something you know (your username and password) and something you have (such as a smartphone, a tablet, a phone, etc.) when you access any Duo-protected services. Duo-supported devices include iPhone, Android, Blackberry, Windows Phone, tablet. Other methods, such as text message, landline, phone call, or a hardware token (upon request), are available as well.


Why am I getting "Access denied. Duo Security does not provide services in your current location" in Duo Prompt?

In order to comply with U.S. regulations, Duo blocks authentications from users 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.

Users attempting to authenticate to a Duo-protected application from an access device with an IP address originating in an OFAC-regulated country or region will be blocked from completing their login and receive an error message. For the full article from Duo, click here.

Please contact the ITS Service Desk at servicedesk@lmu.edu for assistance.


I receive a login request that I did not send. What do I do?

Press Deny to reject the request. You'll be given the opportunity to report it as fraudulent – in which case an email notification will be sent to ITS Information Security. Or you can tap "It was a mistake" to deny the request without reporting it. Pressing Deny three times will lock your user account and email will again be sent to ITS Information Security team.

NOTE: Your password may have been compromised. Reject the login and change your password immediately.

Duo for Students

In an effort to enhance security on sensitive systems and to help keep students' accounts and data protected, ITS implement Duo Mobile for students. Duo Mobile will help keep your LMU/LLS email account secure and prevent unauthorized access to your sensitive data contained in systems such as MyLMU, PROWL, Degree Works, Box, and many others. 

ITS sent out a more detailed email (an example hereto each student group with enrollment steps, where to go for assistance, which systems will be protected by Duo, and why. Students will then receive a Duo enrollment email directly from Duo with a unique link to start the enrollment process.
