Sign in Using Multi-Factor Authentication

Last modified 7/22/2026

You will be prompted to authenticate via Multi-Factor Authentication (MFA) for most campus resources. 

Your experience when signing in will differ slightly depending on which Multi-Factor Authentication method you chose. The available methods are:

  • Microsoft Authenticator App: App-Based Authentication Methods (recommended):
    • App notification (pop-up for approval)
    • App-supplied code (enter code for approval)
  • Phone-Based Methods:
    • Text Message (sends a code)
    • Phone Call (press # to approve sign-in)
  • FIDO2 Security Key
    • Hardware and unique PIN authentication

Use the steps below to assist you in this process. You may also see a visual representation of the process in this video: Using MFA to Log in to Illinois State University Applications.

Multiple MFA verification methods recommended

It is recommended that you set up at least two methods of multi-factor authentication, so you have a backup if one fails. Please see Adding Additional Verification Methods for Multi-Factor Authentication for instructions on setting up additional method(s). To change your default method, see Change the Default Method for Authenticating with MFA.

Authenticator App Verification Methods

The Microsoft Authenticator App is the preferred/recommended method for using MFA at Illinois State University. It provides the most secure experience for our University members. Use the following steps if you have registered for MFA using the Authenticator application as your preferred authentication method. Do note that there are two authentication methods with the Authenticator app:

  • An app-based notification is a pop-up sent directly to your phone that lets you approve/deny the authentication request.
  • An app-based authentication code that is shown within the Authenticator App that you may type into your browser to approve the authentication request

Below are the instructions for each authentication type.

Note:

You will first need to download the Authenticator app to your phone and set up your profile within the application. A link to instructions for doing so may be found at the bottom of this article.


Sign in Using the Microsoft Authenticator App

What you see when you are using the Microsoft Authenticator App will vary depending on whether you are logging in to the Cisco AnyConnect VPN client or another university online resource. Both require MFA authentication, and instructions for each are described below:

  • Signing into a university online resource using the Microsoft Authenticator App Based Notification

  1. Log in to the desired online resource.
  2. You will receive a notification on your mobile device containing a two-digit number (Figure 1). Remember this number:

    Figure 1:
    Approve sign in request message screenshot
  3. You will then see a pop-up asking Are you trying to sign in? This pop-up will contain several features (Figure 2):

    1. An App context. This provides information about what app/device/browser is initiating the MFA approval attempt.

    2. A field labeled Enter number here: You will enter the two-digit number from the previous pop-up in this field.
      1. If you don't remember the two-digit number and can no longer see it, select I can't see the number at the bottom of the pop-up to bring it back into view. Tap once more to return to the 2nd pop-up and enter the number in the provided field.
      2. If you can no longer see the two-digit number and do not have the option to select "I can't see the number," you may need to switch back to the app you were using when you initiated the login and navigate back to enter the number. More information may be found at this link: MFA: Two-Digit Authentication Code is Hidden Behind the Authenticator App.
    3. After you have entered the two-digit number, select Yes to approve the login.
      1. If you did not initiate the login attempt, select No, it's not me, and contact the Technology Support Center at (309) 438-4357 for guidance.

Your login has been authenticated.

If You Are Unable to Use the Authenticator App Currently

If you have the Microsoft Authenticator App set as your primary MFA method and are unable to use it currently, you may click I can't use my Microsoft Authenticator app right now to select another method (Figure 3), provided you already have additional MFA methods configured on your account. A link to instructions for adding additional authentication methods to your account may be found at the bottom of this article.

    1. For more information about using the Cisco AnyConnect VPN client, please see: Using the Cisco AnyConnect VPN Client.
  2. You will receive a drop-down notification on your mobile device asking to “Approve” or “Deny” the Sign-In request (See Figure 4). Tap Approve to approve the sign-in, or tap Deny if you did not initiate the login.
    1. If you select Deny because you did not initiate the login, please contact the Technology Support Center at (309) 438-4357 for guidance.

Your login has been authenticated.

Phone Call Verification Methods

To follow the login instructions below, you will first need to configure your MFA account to use phone verification. A link to instructions for doing so may be found at the bottom of this article.

  • How to Sign In to MFA using the Phone Call Verification

Use the following steps if you have registered for MFA using a phone call as your preferred method of authentication.

  1. Log in to 365.IllinoisState.edu.
  2. You will get a notification that ‘your phone is being called and to answer to continue’ (See Figure 5).

    Figure 5:
    Approve sign in request message
  3. You will receive a phone call asking you to press the Pound Key # to verify your Sign-in. Once you have pressed the Pound (#) key on your phone, you will be told that your verification was successful, and you can hang up.

Your sign-in is now authenticated.

  • How to Sign In to MFA using SMS/Text Message Verification

Use the following steps if you have registered for MFA using a phone text message as your preferred method of authentication.

  1. Log in to the desired online ISU resource, and you will receive the prompt below (Figure 6):

    Figure 6:
    Enter code pop-up
  2. Open up the text message once received to get the code (Figure 7). Then enter the code in the field provided in the prompt shown above.
