Overview of User Login Change & Microsoft Duo Authentication

This article contains an overview over the User Login Change and Microsoft Duo Authentication change for faculty, staff, emeritus, and administrative accounts happening in 2020-2021.

Please note that some groups had the User Login Change and the Microsoft Duo Authentication change applied to their accounts separately. This guide is for users who had both changes applied at the same time. Please check the email you received from IT Communications to see which change(s) are being applied to your account or contact the IT Help Desk at [email protected] or 657-278-7777.

What is happening?

There are two components to this change:

  1. There are some apps that use an [username]@ad.fullerton.edu login for CSUF faculty and staff. This login is being updated to [username]@fullerton.edu for all CSUF faculty and staff.
  2. To improve the security of your Outlook email and Office apps, you will now be prompted to authenticate with Duo two-factor authentication (2FA) when logging into Office apps and apps that use Microsoft authentication.

When is this happening?

This update is happening in phases. You will receive an email from IT Communications with the specific date/time that your account is being updated. If you are not sure when you are being updated, please contact the IT Help Desk at [email protected] or 657-278-7777.

Which apps are affected?

  • Microsoft Outlook desktop app on PC and Mac
