Duo Multifactor Authentication

Secure Your Campus Login with Another Layer of Protection

Keep your private and confidential information safe with this additional layer of authentication protection. Duo multifactor authentication adds a second layer of protection to CampusID login to prevent unauthorized access to accounts in campus systems that use single sign-on. Faculty, staff and student employees have access to this service. The service has also begun being applied to some Office 365 faculty and staff email accounts. If you would like Duo turned on for your Office 365 faculty or staff email account as this time, contact the IIT Service Desk.

Get Started

Duo Multifactor Authentication acts as a second layer of defense against unauthorized login to your CampusID account, protecting access to the information in your campus accounts even if your CampusID password is guessed or stolen. The service uses a mobile device or phone to verify that the person logging in to your account is you.

Note: If you received an email from technology@gsu.edu or passwordmanager@gsu.edu stating that you’ve been added as part of a roll-out group to Duo, you do not need to request registration.

What is Duo Multifactor Authentication?

Duo links to your CampusID login and acts as a secondary protective measure, in addition to your CampusID password, to ensure the person logging in is you. Each time you attempt to log in to any campus service protected by Duo, Duo will send a notification to a mobile device or phone associated with your account that you must approve, ensuring that each successful login attempt is being made by you.

Why Use Duo Multifactor Authentication?

Duo helps protect your campus accounts from unauthorized access in the event your CampusID password is compromised. Even if your password were guessed or stolen, the attacker would not be able to sign in without authorization using Duo. Duo increases the security of university systems and resources, protecting important sensitive and confidential information.

3. Log In Using Your CampusID with Duo

Once you set up a mobile device or phone to log in with Duo, it may take up to 24 hours before multifactor authentication becomes active for your account. Once Duo multifactor authentication is active, you will be prompted to verify your identity using Duo each time you log in to an application that is protected by the university single sign-on system. Protected campus systems include OneUSG, iCollege and many others, but do not include the faculty and staff Office 365 email system at this time.

When you set up a device to log in with Duo, you can pick from these options to verify your attempt to log in.

  • Push Notification: A notification sent to your mobile device or phone using the Duo app (must be installed) for you to approve or deny your log in attempt. Recommended: This is the recommended option if you have a mobile device or phone on which you can install the Duo mobile app.
  • Phone Call: A computer-generated call to your phone that includes a code for you to enter to approve your log in attempt.
  • Passcode: A one-time, randomly-generated code located in the Duo app that you can enter to approve your login attempt. You might choose to use this option if you have the Duo App installed on your device but do not have access to a wireless network or cellular network at the time of login.
