Troubleshooting

Why am I not receiving push notifications?

Android: In most cases, if your phone is on and the screen is active, you can receive messages, and the app will open for a Duo Push request. On the other hand, if the phone is on, receiving messages, and the screen is inactive (dark), you should receive an alert (a sound or vibration) and a message indicating that you have received a Duo Login Request. Open the Duo app and Approve or Deny the request. 

Apple: Apple phones don't allow this. If your phone is on and can receive messages, you should receive a message asking, "Are you logging in to Fischer Web SDK?". You can click the request and approve or deny it. In some cases, Apple devices may not display a message indicating that you have received a Duo Push Request. If this happens, open the Duo app and Approve or Deny the request. 

Report all Duo Push messages you did not generate to the IT Service Desk. This may indicate that someone is attempting to access your account without authorization and that your password may be compromised. Deny the push notification, then confirm it’s a fraudulent attempt. You should change your ISU password if this occurs.

I don't have my Duo Device (phone, etc) how do I log in?

  • Please contact the IT Service Desk for exceptional situations in which you need to log in but do not have your registered device. They will verify your identity and provide you with a temporary pass code. 

 

What should I do if I get a Duo push notification I didn't expect? 

Report all Duo Push messages you did not generate to the IT Service Desk. This may indicate that someone is attempting to access your account without authorization and that your password may be compromised. Deny the push notification, then confirm it’s a fraudulent attempt. You should change your ISU password if this occurs.

NoteS:

  • If Duo states that your account is locked out, Please contact the IT Service Desk to resolve this.
  • If you have recently changed device, please contact the IT Service Desk. After verifying your identity, they can help you reactivate your device or set up a new one.
