Troubleshooting

AuthenticationView Details

Why don't I get push notifications?View Details

Android: Under most circumstances, if your phone is on, can receive messages, and the screen is active, the app will pop open for a Duo Push request. On the other hand, if the phone is on, able to receive messages, and the screen is inactive (dark), you should get an alert (a sound or vibration) and a message that you have received a Duo Login Request. Open the Duo app and Approve or Deny the request.
- Go to detailed instructions from Duo to resolve this issue.
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 the request. Under some circumstances, some Apple devices do 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.
- Go to detailed instructions from Duo to resolve this issue.

Note: If push notifications are still malfunctioning, Reactivate Duo Mobile.

My account is LOCKED due to excessive authentication failures.View Details

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

Receiving a push notification that you did not request may signify someone is attempting unauthorized access to your account, and your password may be compromised.
