Two-factor Authentication

Two-factor authentication also referred to as multi-factor authentication, provides an additional layer of security when logging in to a website. Two-factor authentication is becoming the standard in cybersecurity. Google, Apple, and other services all have their two-factor authentication methods. In short, passwords are no longer sufficient in protecting our sensitive data; we’ve got to add another layer of security to our accounts.

Common FAQ’s for DUO Authentication

You do not have to have a smartphone for this option.

     

  • Selecting this option will allow you to bypass DUO authentication for the next 60 days. This only works if cookies are enabled, and you are logging in from the same computer and browser. You will still be prompted to verify once – with your username and password. You will not be able to access your settings on that particular browser during the 60 days. Please note that if you have tools or policies running that regularly delete or clean cookies, the remember me feature will not work. If you do need to access your settings (perhaps to add another device), just try another browser or visit the FDU Self-Service Portal. Remember me will not work if your browser is set to private browsing mode.

  • The remember me feature relies on browser cookies. For remember me to work, your Internet browser must allow cookies to be stored. Visit your browser content settings to ensure cookies are being stored. Some departments on campus do not allow cookies to be stored. If the remember me feature does not work on your browser, check with desktop support in your area.

  • If you do not have your device with you, you can obtain a batch of temporary passcodes. To obtain a temporary passcode, call the Fairleigh Dickinson University Technical Assistance Center (UTAC).  Each of the passcodes can only be used once and will expire in 7 days.

    NOTE: If you have lost your device, please report it to the Fairleigh Dickinson University Technical Assistance Center (UTAC).  We want to ensure someone else does not maliciously authenticate your account with your device.

  • DUO is available to all faculty,staff, and Students. At this time, DUO is not available to FDU retirees, past employees, or alumni.

  • Yes, the passcode option on the DUO app does not require WiFi or cellular connectivity, it even works on airplane mode. To use this option, visit the DUO app on your smartphone, and tap the key icon to obtain a passcode. Enter the passcode into the DUO prompt when logging into any website that requires DUO authentication.

  • DUO Authentication is required by any application the utilizes the university Single Sign-On (SSO) service.  Examples of some websites that require DUO authentication are listed below.

    • WebAdvisior
    • WebCampus
    • Office365 (Office365.fdu.edu)
    • Blackboard
    • Zoom
  • You may have trouble receiving push requests if there are network issues between your phone and Duo’s service. Many phones have difficulty determining whether to use the Wi-Fi or cellular data channel when checking for push requests and simply turning the phone to airplane mode and back to normal operating mode again often resolves these types of issues, if there is a reliable internet connection available. Similarly, the issue may be resolved by turning off the Wi-Fi connection on your device and using the cellular data connection.

    Check the time and date on your phone and make sure they are correct. If the date and time on your phone are manually set, try changing your device’s configuration to sync date and time automatically with the network.

    iOS users can run a troubleshooting tool from within Duo Mobile version 3.32.0 or later. To run the tool:

    1. Open the Duo Mobile app on your iOS device and tap the Edit button in the top left of the accounts list screen, then tap the name of the account for you aren’t receiving push requests.
    2. Next, tap the Get Started button in the “Missing Notifications?” section of the “Account Details” screen.
    3. Duo Mobile performs the test. If any step fails, you’ll receive further troubleshooting suggestions. After taking the suggested actions, press “Run test again” to retry.

    The steps that Push Troubleshooting performs automatically are as follows:

    • Check device settings.
    • Check internet connectivity.
    • Check that the device can contact Duo’s cloud service.
    • Attempts to send a test Duo Push notification.

    Should none of these actions help, see the Duo Knowledge Base for additional iOS and Android troubleshooting steps.

    If you can’t get Duo Push working on your own, you can log in with a passcode generated by the Duo Mobile app and send a new activation link to your phone.

    If you’ve tried the suggestions here but can’t get Duo Push working or reactivate your device yourself, please contact the Fairleigh Dickinson University Technical Assistance Center (UTAC).
