Setting Up the Time Based One Time Passcode Authentication Method
Last modified 7/23/2026
Time-based one-time passcode (TOTP) is a standard protocol. Azure MFA, which powers Illinois State University's MFA, supports authenticators that support the TOTP protocol. Primary examples include Google Authenticator, Duo Mobile, and password managers such as LastPass and Bitwarden.
Note:
This method provides an additional option for end users who do not have, or do not want to use, a personal phone/smartphone, and do not want a hardware token either.
- Navigate to the ULID Account Management Portal.
- Log in with your ULID and password.
- Upon logging in, click the Change MFA Devices button next to MFA. (See Figure 1).
Figure 1: - Press the Manage Devices button located at the bottom. (See Figure 2).
Figure 2: - You may be prompted to log in with your ISU email account or to authenticate your login with your preferred MFA method (Authenticator app, phone call, text, etc.).
- Once you are in the Security Info tab, you should see the Default Sign-in Method section with the Authenticator app - notification method as your main method. To change it to One-Time Password, click Change, then select Authenticator App or Hardware Token - Code from the drop-down menu that appears (See Figures 3 and 4).
