To reconnect Duo Mobile, you need to restore your device from a backup before opening the app, then use the Reconnect button to link your existing Duo-protected accounts. This process works on both iPhone and Android, but the exact steps differ depending on whether you are setting up a new phone or recovering from a factory reset.
Before you reconnect Duo Mobile: The two scenarios that require reconnection
You will need to reconnect Duo Mobile in two situations: after switching to a new phone or after performing a factory reset on your current device. The critical prerequisite is restoring your device backup before opening Duo Mobile. If you open the app before restoring, your accounts may be permanently lost. On iPhone, restore from an iCloud, iTunes, or Finder backup. On Android, ensure Google Backup has run since Duo Mobile was installed and that you have enabled a lock-screen PIN, pattern, or passcode. Duo Restore must also be enabled by your organization’s administrator for the reconnection feature to work.
Reconnect Duo Mobile on iPhone
- Restore your iPhone from an iCloud, iTunes, or Finder backup before opening Duo Mobile.
- Open Duo Mobile after the restore completes.
- Tap Reconnect next to the account you want to reconnect.
- Sign in to the Duo-protected application and complete the authentication prompt.
If Duo Restore is not enabled or the account is a third-party account, you may instead see Scan a QR code or Enter activation code after tapping Reconnect. Duo’s restore page says that after tapping Reconnect in Duo Mobile, you may be shown Scan a QR code or Enter activation code. Duo’s iOS restore guidance says that third-party account backups do not automatically reconnect Duo-protected accounts.
Reconnect Duo Mobile on Android
- Install Duo Mobile from Google Play if it is not already installed.
- Open the app and tap Get My Account Back on the welcome screen.
- Select the Google account that was used for Duo Restore.
- Tap Reconnect next to the Duo account.
Android Instant Restore requires Duo Mobile version 4.83 or higher, Google Backup enabled in Android System Settings, a backup that has run since Duo Mobile was installed, a lock-screen PIN/pattern/passcode, and Third-party account reconnect turned on in Duo Mobile’s instant restore settings.
When the Reconnect button does not appear
If the Reconnect button is missing, you have fallback options. First, you can scan a QR code or enter an activation code, these options may appear after tapping Reconnect if Duo Restore is unavailable. If your organization has enabled self-service device management, you can reactivate Duo Mobile through the Duo Prompt or Universal Prompt using phone callback or SMS authentication. For Duo-protected accounts, Duo says to recover through the My Settings and Devices page from the Duo prompt to reactivate the account. As a last resort, contact the IT Help Desk or your Duo service administrator for account reactivation.
Troubleshooting Duo Mobile reconnection issues
Common fixes include checking your internet connection, verifying that your device’s time and date settings are accurate and set to automatic, ensuring Duo Mobile is updated to the latest version, and confirming that Duo Restore was enabled by your administrator. If Duo Restore is not enabled, or if the backup contains third-party accounts without a recovery password, you will need to use the QR-code or activation-code path. Duo documents that restoring third-party accounts requires a recovery password when Duo Restore is used. If none of these steps work, contact your IT administrator, Duo Support will not help troubleshoot cases where accounts cannot be recovered by Duo Restore or other means.
