Google Authenticator transfer is the built-in process for moving all your 2FA accounts from one phone to another. The app supports two methods: a QR code export that works across platforms, and a Google Account sync that works when both devices use the same Google account. This guide covers how to use Google Authenticator transfer and what to do when something goes wrong.
1. What Is the Google Authenticator Transfer Feature?
Google Authenticator stores time-based one-time passwords (TOTP) for every account you have protected with 2FA. These codes are generated locally from a seed value that was shared when you first set up 2FA for each account. Moving to a new phone means moving those seed values.
Before starting the transfer, three preparation steps reduce the chance of problems mid-process.
Check whether Google Account sync is enabled. Open the Google Authenticator app and tap your profile icon in the top right. You can check whether Authenticator is connected to a Google account by opening the app and viewing the account section near your profile settings. If it is off, the sync method will not work, and you will need the QR export method instead.
Update the app on both devices. Keeping both devices updated helps ensure compatibility with the latest transfer and sync features. The export and import flows look identical across versions, but only the current versions support all account types.
Keep access to your old phone. The QR export method requires both phones to be on and functional at the same time. Do not factory reset or return the old phone before confirming the transfer is complete and all codes work correctly on the new device.
2. How to Transfer Google Authenticator to a New Phone
Two transfer methods are available. The QR export method works in all situations. The Google Account sync method is faster but requires that cloud sync be enabled on the old device before the transfer.
2.1 QR Export Method
This is the most universally compatible method and the one to use if both phones are accessible and functional.
Step 1: Export accounts from your old phone.
Open Google Authenticator on the old phone. Tap the menu icon (three vertical dots) in the top right corner. Select Transfer accounts, then Export accounts. You may be asked to verify your identity using your device PIN, fingerprint, or face unlock. Select the accounts you want to transfer. You can select all or choose specific ones. Tap Next. The app generates a QR code containing all selected accounts.
Step 2: Import accounts on your new phone.
Install Google Authenticator on the new phone if it is not already installed. Open the app and tap Get Started. Select Import existing accounts. Tap Scan QR code and point the new phone’s camera at the QR code displayed on the old phone. If you have many accounts, the app may generate multiple QR codes. Scan each one in sequence.
Step 3: Verify the transfer was successful.
All imported accounts should now appear in the app on the new phone. Log into one or two of the protected services and confirm the codes generated on the new phone are accepted. Do not delete the accounts from the old phone until you have verified at least two or three services are working correctly.
2.2 Google Account Sync Method
If sync was enabled before switching devices, signing into the same Google account may restore your Authenticator accounts automatically.
Step 1: Link Google Authenticator to your Google Account.
On the old phone, open the app and tap your profile icon. Tap Use without an account if sync is off, or confirm your Google account is shown with a cloud sync icon. If sync was not previously enabled, enable it now. Your accounts will upload to your Google Account storage.
Step 2: Sign in on your new device.
Install Google Authenticator on the new phone and sign in with the same Google account. All synced accounts restore automatically. This method works even if the old phone is no longer accessible, as long as sync was enabled before the old device was lost or reset.
3. Switching Between Android and iPhone (or Vice Versa)
The QR export method is the most reliable option for cross-platform transfers, although synced accounts may also restore automatically when signing into the same Google account. The steps are the same as the QR method above, but the installation step on the new device differs by platform.
3.1 Android to iPhone
Install Google Authenticator from the App Store on the iPhone before starting. Use the QR export method from the Android device. The app interface on iOS is nearly identical to Android, so the import flow looks the same. After importing, sign in to your Google account within the iOS app to enable cloud sync going forward.
3.2 iPhone to Android
Install Google Authenticator from the Google Play Store on the Android device. Use the QR export method from the iPhone. The process is identical. If you previously had sync enabled on the iPhone, the accounts may already be in your Google Account and can be restored by simply signing in on the Android device.
3.3 What Stays the Same During Transfer
All 2FA accounts and their associated seed values transfer completely. The codes generated on the new device will be identical to those that would have been generated on the old device at the same moment. In most case, no accounts need to be re-registered with the services they protect. Your accounts and their 2FA protection remain active without any changes on the service side.

4. Common Transfer Problems and Fixes
Most transfer problems fall into four categories. Working through these in order resolves the majority of issues.
- Missing accounts after transfer
If some accounts are missing, check whether all QR codes were scanned during the import process. For Google Account sync, make sure you’re signed in with the same Google account on both devices.
- No access to the old phone
If the old phone is unavailable, try signing in to Google Authenticator with the same Google account if sync was previously enabled. Otherwise, you may need to use backup codes or account recovery options provided by the affected services.
- Sync not working
Confirm that both devices are connected to the internet and using the same Google account. If the issue continues, update the app or use the QR export method instead.
- Invalid verification codes after transfer
Make sure your device’s date and time are set automatically. If codes are still rejected, try signing in with a backup code and reconfiguring two-factor authentication for that account.
5. After the Transfer
Three steps confirm the transfer is fully complete and protect against future loss.
- Confirm codes are working: Before removing anything from the old phone, test a few accounts on the new device to confirm the generated codes work correctly.
- Remove the old device: Once you’ve verified the transfer, remove the accounts from the old phone or reset the device if you no longer plan to use it.
- Keep backup recovery methods: Consider saving backup codes or other recovery options for important accounts. They can help you regain access if you ever lose your device in the future.

6. FAQs
Can You Use Google Authenticator on Two Phones at Once?
Yes, if both phones are set up using the same seed. The QR export method installs the same accounts on both devices, and both will generate valid codes simultaneously. Google Account sync also keeps accounts available on multiple signed-in devices.
Is Google Authenticator Transfer Safe?
The QR export transfer is safe if done in a private location where no one can photograph or record the QR code. The code contains all your account seeds in exportable form, so anyone who scans the export QR code can import the associated authentication secrets and generate future verification codes for those accounts.
What Happens to the Old Phone After Transfer?
The accounts remain on the old phone until you manually delete them or factory reset the device. They continue to generate valid codes. This is why removing the accounts from the old phone after confirming the transfer is an important security step.
7. Conclusion
Google Authenticator transfer works reliably when both devices are available and the app is up to date. The QR export method handles every scenario, including cross-platform moves. The sync method handles transfers when only one device is available at a time.
The critical steps in how to use Google Authenticator transfer are verifying the transfer before wiping the old phone, testing codes on actual logins rather than just checking they appear, and enabling sync on the new device so the next transfer is faster and safer.
