What is MFA @ CSU?

Clayton State University Information Technology Services has implemented MFA to protect employees and students from identity theft and to safeguard Office 365 (Email, OneDrive and Sharepoint) and OneUSG information. It has become a best practice at universities, financial institutions and online email providers.

MFA is enforced for all OneUSG and Office365 login attempts.

Configure Contact Information

In order to use MFA, add your contact information in the Campus Directory.


1. Browse to DIRECTORY

2. Click LOG IN to update your information.

3. Enter your CSU credentials and click LOG IN.

4. Upon logging in, please update the Personal Contact Information section. Home Phone, Mobile Phone, and Personal Email Address are required for the MFA process.

5. After entering in your information, scroll down to the bottom of the screen and click SAVE.

How MFA Works

When navigating to Office 365 or OneUSG, you will be redirected to the federation page and asked to choose a verification method that will be sent to your Mobile Phone provided in the Campus Directory.

Send notification via Phone Call

You will receive a call on your mobile device. When you answer the call, follow the instructions to approve access. The screen will automatically change, logging you into your account.

Send notification via Text

You will be texted a code on your mobile device. Enter the verification code on the login page. The screen will automatically change, logging you into your account.

Send notification to my Mobile App

You will receive a message through the Microsoft Authenticator App. Select Approve or Deny access. If Approved is selected, the screen will automatically change, logging you into your account.


Download and install the Microsoft Authenticator app

The Microsoft Authenticator app can be used to sign into accounts when using two-factor verification. It should be noted that the authenticator app is one verification option out of three and you are not required to install it.

When installing the app, make sure to read the terms and conditions and if you agree, grant it access to your camera for you to be able to scan the QR code later.

Install the latest version of the Microsoft Authenticator app, based on your phone’s operating system.

  • On your Android device, go to Google Play to DOWNLOAD and install the Microsoft Authenticator app.
  • On your Apple iOS device, go to the App Store to DOWNLOAD and install the Microsoft Authenticator app.

1. Browse to MFA LOGIN and sign in with your CSU credentials.

2. You will be prompted to provide a one-time passcode. Click Authenticate and a text will be sent to your mobile device with the authentication code.

3. In the My Account menu, click Activate Mobile App.

4. Click Generate Activation Code Activation Code.

5. A QR code will appear on your screen (simular to the one shown below). Leave this screen up for the next step.

6. Open the Microsoft Authenticator app on your mobile device and select the option to add an account. When prompted for what type of account you are adding, select Work or school account. After you select this option you will get a screen on your mobile device to scan the QR code. Position the camera of your mobile device over the QR code until it successfully scans the code and adds the account.

7. Once your account has been added to the Microsoft Authenticator app switch back to your browser and click Complete Activation. You will receive a message on screen saying that activation is complete. The app is now ready for use.

8. In the My Account menu, click Change Method.

9. Select the method you prefer to use to use from the drop-down menu.

10. After making your selection click on the Save button.

11. Even though you may have selected one of these options as your default, you will still be presented with all three options when logging in to Office 365 via the web or OneUSG on a browser, as shown in the screenshot below. When presented with the three options you may choose any of them. For other applications, such as adding email on your mobile device, MFA will use the option you selected in the previous step.


Do I need to authenticate every time I log on?

For OneUSG, you need to authenticate every time you log on. For logins to Office 365 via the web, you have the option to have your browser “remember” you and will see this option when you log in.

You will not need to log in every time you open Outlook or other apps such as Teams, but occasionally you may be prompted by these programs to sign in again and you will need to authenticate at that point.

What if I am out of the country?

If you do not have mobile service while out of the country, you will need to install the Microsoft Authenticator app, which will work with Wi-Fi service.

What if I change my number?

If you change your number, update your information in the Campus Directory. If you are keeping the same mobile device and just changing the number, the Microsoft Authenticator app will still work. If you are getting a new number and a new mobile device, the app will need to be installed again as outlined in this document.
