This article provides solutions to Common issues.
Contact out Technology Help Desk at 262-595-2444, if you have an issue that isn't listed here.
- I need to reactivate Duo Mobile.
- I have stopped receiving push notifications on Duo Mobile.
- I lost my phone.
- My hardware token stopped working.
- I am running iOS 8 (or lower) and I am not able to install the current version of Duo Mobile from the App Store on my device.
- I am using Microsoft Internet Explorer and the Duo Prompt does not display correctly.
I need to reactivate Duo Mobile
If you get a new phone you'll need to re-activate Duo Mobile. You may enroll your new device yourself using Duo's device management portal if self-service is enabled. Otherwise, ask your administrator to send you a new activation link.
Choose your platform on the left for specific activation instructions.
If your administrator enabled Duo Mobile's backup and restore functionality and you previously backed up your Duo Mobile accounts then you can restore your accounts to Duo Mobile on your new phone (same platform as the original device i.e. Android to Android and iOS to iOS) via the guided recovery process. See the full Duo Restore guide here.
I have stopped receiving push notifications on Duo Mobile.
You may have trouble receiving push requests if there are network issues between your phone and our service. Many phones have trouble determining whether to use the WiFi 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 sort of issues, if there is a reliable internet connection available. Similarly, the issue may be resolved by turning off the WiFi 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.
If you can't get Duo Push working on your own and your administrator has enabled Duo's device management portal, you can log in with a passcode generated by the Duo Mobile app and send a new activation link to your phone. See the My Settings & Devices guide for instructions.
If you've tried the suggestions here but can't get Duo Push working or reactivate your device yourself, please contact your organization's Duo administrator to request reactivation of Duo Mobile.
I lost my phone.
Contact your Duo administrator immediately if you lose your phone or suspect that it's been stolen!
If your organization enabled Duo's self-service feature and you had previously enrolled a second authentication device you can use My Settings & Devices to delete your lost or stolen phone.
If you aren't able to log in to Duo at all then your Duo administrator can disable the missing phone for authentication and help you log in using another method.
While it's important that you contact your administrator if you lose your phone, remember that your password will still protect your account.
My hardware token stopped working.
Contact your administrator if your token stops working or if you can't log in with the passcodes it generates.
Your token can get "out of sync" if the button is pressed too many times in a row and the generated passcodes aren't used for login. In some cases this can happen by accident if the token is stored next to other objects in a pocket, backpack, etc. Your administrator will ask you to generate three passcodes in a row and can attempt to resynchronize the token.
I am running iOS 8 (or lower) and I am not able to install the current version of Duo Mobile from the App Store on my device.
The minimum supported operating system version for Duo Mobile 3.17.0 and above is iOS 9. Users installing Duo Mobile for the first time with devices running iOS versions below 9 must download the generally available Duo Mobile app release from the App Store on a newer Apple device running iOS 9+, while signed in with the same iTunes account you plan to use with your iOS 8 or lower device.
Then, browse to "Purchased Items" on your iOS 6, 7, or 8 device to install Duo Mobile. You will will receive the latest compatible version of Duo Mobile (3.16.7).
Contact your administrator if further assistance is required.
I am using Microsoft Internet Explorer and the Duo Prompt does not display correctly.
For the best results we do not recommend using Internet Explorer's Compatibility View with Duo authentication. You may be able to turn off Compatibility View yourself.
From the Address bar:
If the Compatibility View button displays in the Address bar to the right of the page address, you can click the button to exit Compatibility mode.
From the Internet Explorer Tools Menu:
In the Internet Explorer browser window press the Alt key to display the menu bar. Navigate to Tools → Compatibility View settings and make one or more of the following changes:
- Remove the website where you use Duo authentication from the "Websites you've added to Compatibility View"
- Uncheck the "Display all websites in Compatibility View" option if present and enabled.
- Uncheck the "Display intranet sites in Compatibility View" option.
Click the Close button to save your change.
Contact your administrator if the Duo Prompt continues to display incorrectly.
Please contact your system administrator if you have an issue that isn't listed here.
