To log into Duo Mobile on a new phone, you will either reactivate your existing account if you kept the same phone number or add the device as new if your phone number or operating system changed. If you are locked out of all enrolled devices, you must contact your organization's IT help desk for account recovery assistance.
How to log into Duo Mobile on a new phone: Overview of the two main scenarios
There are two primary scenarios for transferring Duo Mobile to a new phone. If you kept the same phone number, you can reactivate your existing Duo account through your organization's device management portal. If you have a new phone number or are switching between different operating systems (e.g., Android to iOS), you will need to delete your old device from the portal and add the new one as a fresh device. If you cannot access any previously enrolled authentication methods, you will need to contact your Duo administrator or IT help desk for assistance.
Download and install the Duo Mobile app
First, download and install the Duo Mobile application from your new phone's app store. For Android devices, use the Google Play Store; for iOS devices, use the Apple App Store. After installation, grant the app permission to access your camera, as this is required for scanning QR codes during setup.
Access your organization's Duo Device Management Portal
Navigate to your organization's Duo Device Management Portal or any web-based application that displays the Duo Prompt. This is the starting point for adding or reactivating your device.
Authenticate with an existing method
Before you can add your new phone, you must verify your identity using an existing authentication method. Your options include entering a text message passcode sent to your registered phone number, answering a phone call to your registered number, or approving a push notification sent to your old device if it is still accessible.
Reactivate Duo Mobile with the same phone number
If you have a new phone but kept the same phone number, locate your previous phone in the device management portal. Select the option labeled "I have a new phone," "Re-enroll," or "Reactivate." Follow the on-screen instructions, which typically involve displaying a QR code on your computer screen. Open the Duo Mobile app on your new phone, tap "Add Account" (or the plus "+" sign if you have existing accounts), select "Use QR code," and scan the QR code displayed on your computer screen with your new phone's camera. During the setup, you'll have the opportunity to transfer your existing accounts to the new device. This involves scanning QR codes or manually entering the provided information for each account. During the activation process, you'll have the opportunity to verify the linked accounts by generating test 2FA codes.
Add Duo Mobile with a new phone number or different operating system
If you are switching to a new phone with a different phone number or a different operating system (e.g., Android to iOS), you must first delete your old device from the management portal. Then, add the new device as a new device. Note that Duo Restore functionality only works for the same mobile platform (e.g., Android to Android or iOS to iOS); it cannot restore backups across different platforms.
What to do if you cannot access any enrolled devices
If you do not have access to any previously enrolled authentication devices, you will need to contact your organization's Duo administrator or IT help desk for assistance. They can help you recover your account and set up Duo Mobile on a new phone.
Frequently Asked Questions
Can I use Duo Mobile on multiple devices at the same time?
Yes, Duo Mobile supports using multiple devices for the same account. You can install the app on several phones or tablets and link them to your account for added convenience.
What if I lost my old phone and cannot receive a push notification?
If you have lost your old phone, you can still authenticate using a text message passcode or a phone call to your registered phone number, provided you still have access to that number. If you cannot use any method, contact your IT help desk.
How do I set up Duo Mobile on a new phone without my old phone?
To set up Duo Mobile on a new phone without your old device, use your organization's Duo Device Management Portal and authenticate via SMS passcode or phone call to your registered number. Then follow the reactivation or new device steps.
Can I transfer Duo Mobile from an Android to an iPhone?
Yes, but you cannot use Duo Restore because it only works between the same mobile platforms. You must delete your old Android device from the portal and add your new iPhone as a new device.
How do I set up a Duo Mobile account for the first time?
To set up a Duo Mobile account for the first time, download the app from your device's app store, then follow the enrollment link or QR code provided by your organization's IT department or through their web portal.
How does this differ from how to set up Microsoft authenticator on new phone?
While both apps use QR code scanning for setup, Duo Mobile requires you to authenticate through your organization's portal before adding a device. Microsoft Authenticator often allows account recovery through a cloud backup or by signing into your Microsoft account directly on the new device. The 6-digit codes are time-based and refresh periodically.
