Single Sign-On for Office 365

Beginning on Wednesday, July 24, 2019, you will access the applications available through your @usc.edu O365 account via the same USC single sign-on (SSO) process that you currently use to access services such as Blackboard, Workday, MyUSC, and others.

What Is Single Sign-On (SSO)?

In order to allow you to access multiple university-provided services without re-entering your credentials, USC provides a single sign-on process (commonly referred to as the red NetID login screen).

Because USC’s SSO relies on a technical protocol referred to as Shibboleth, you may also hear this process referred to as Shibboleth single sign-on.

What Is the USC Microsoft Office 365 (O365) Account?

Your USC O365 account provides access to a number of applications, including email, calendar, Microsoft Office Online, Microsoft Office downloads, OneDrive for Business, Skype for Business, and other applications. While all USC account holders have a USC O365 account, some account holders may access these applications through their local school- or unit-based system.

  • If you access these applications with your @usc.edu credentials, SSO will apply.
  • If you access these applications through a school- or unit-based login, SSO may not apply.
  • If you use USC Gmail for your university email, SSO already applies.

Please note: At this time, students do not have access to the email and calendaring functions of USC O365 accounts.

How Will SSO Affect My Access to My USC O365 Account?

Most account holders access their USC O365 accounts through different devices (desktop, laptop, and mobile) and in a variety of ways—Web browsers, mobile apps, and Windows and Mac standalone clients and apps. While the impact of this change depends on the device and access method that you use, please note that most account holders will experience minimal inconvenience.

If You Check Your O365 Email using the Mobile Email Apps:

You will only need to log into mobile email apps via SSO once a year or when you change your password.

If You Check Your O365 Email using the Outlook Client for PC or Mac:

You will only need to log into Outlook via SSO twice a year or when you change your password.

If You Use Mobile and Desktop Versions of Other O365 Apps:

You will need to log into mobile and desktop versions of other Office 365 apps, such as OneDrive for Business and Microsoft Teams via SSO twice a year or when you change your password.

Duo and Office 365

If you currently use Duo two-factor authentication (2FA) to access other USC NetID services, you will also be required to use Duo to access your USC O365 account through SSO.
