How to Use Google Authenticator Transfer: Move Your 2FA Codes to a New Phone

Transferring Google Authenticator to a new phone requires either signing into your Google Account on the new device (which syncs codes automatically) or using the in-app QR code export to move them manually. Just reinstalling the app is not enough — your codes do not carry over on their own.

Two-factor authentication is widely considered one of the most effective ways to protect online accounts from unauthorized access, as detailed in The Verge's guide to setting up 2FA — which is exactly why getting the transfer right matters.

Two Ways to Transfer — At a Glance

There are exactly two methods for transferring Google Authenticator codes:

Method 1 — Google Account Sync: Sign into your Google Account inside the Authenticator app on your new device. Your codes sync automatically. No old phone needed.

Method 2 — Manual QR Export: On your old device, generate a QR code from inside the app. Scan it with your new device. Both phones need to be present.

Which one should you use? If you have a Google Account linked to the app, Method 1 is faster and works across platforms. If you use Authenticator without a Google Account — or need to transfer third-party accounts that were never synced — Method 2 is the right path.

Before You Start — What to Check First

A few things are worth confirming before you begin, otherwise you may run into errors mid-transfer.

App Version Requirements

The sync feature requires:

• Android: Google Authenticator version 6.0 or above
• iOS: Google Authenticator version 4.0 or above

Check your version in the App Store or Google Play Store. If you are running an older version, update it before proceeding. In practice, most users on modern phones already meet this requirement — but it is worth confirming if your phone has not been updated recently.

What You Need Ready

• Access to your old device (for manual transfer only)
• Your new device with the Google Authenticator app installed
• Your Google Account credentials (for sync method)
• A stable internet connection (for sync method)

If you no longer have access to your old device, skip ahead to the lost device section below.

Method 1 — Transfer Using Google Account Sync

This is the recommended approach for most users. It is faster, requires no scanning, and works even if you are switching between Android and iPhone.

What This Method Actually Transfers

Codes that are saved and linked to your Google Account will sync to the new device. What's often overlooked is that third-party accounts — banking apps, social platforms, or anything else you added to Authenticator — only transfer via this method if they were saved under your Google Account in the app. If they were stored locally, they will not appear after sync.

How to Check Whether Your Codes Are Already Synced

Open Google Authenticator on your current phone and look at the top-right corner:

• Green cloud icon with a checkmark — your codes are synced to your Google Account
• Gray cloud icon with a slash — codes are stored locally only; sync is off

If sync is off and you want to enable it before transferring, tap the profile icon, select your Google Account, and tap Allow when prompted to save codes to that account.

Steps to Transfer via Google Account Sync (Android and iOS)

1. On your new device, download and open the Google Authenticator app.
2. Tap Get Started.
3. Sign in to the same Google Account you used on your old device.
4. Your codes will appear automatically — no scanning required.

That is the entire process. In practice, codes typically appear within a few seconds of signing in. As reported by TechCrunch, when the sync feature launched, codes stored locally on a single device could previously be lost permanently if that device was misplaced — the cloud backup was the fix for exactly that problem.

The 7-Day Delay — What It Means and Why It Happens

After syncing to a new device, Google may take up to 7 days to recognize Google Authenticator as a trusted sign-in method for your Google Account. This is a deliberate security measure, not a bug. It gives you time to detect and respond if someone else is trying to access your account without permission.

If you have a passkey or hardware security key linked to your Google Account, you may be able to speed up this trust process.

Method 2 — Transfer Manually Using QR Code Export

This method works without a Google Account and transfers every account stored in the app — including third-party services like Facebook, banking apps, or any other service using 2FA. You need access to both your old and new phones.

Important: Codes Stay on Your Old Device

After the transfer, codes are not removed from your old device. They continue to work there unless you manually delete them. If you are moving to a new phone permanently, it is worth deleting the old codes once you have confirmed everything works on the new device.

Cross-Platform Limitation

The QR export method does not work between Android and iPhone directly. If you are switching platforms, use Method 1 (Google Account sync) instead, which handles cross-platform transfers without any issues.

Steps to Manually Transfer on Android

1. On your new Android phone, install Google Authenticator and tap Get Started.
2. Tap Scan a QR code when prompted.
3. On your old Android phone, open Google Authenticator.
4. Tap the three dots (top right) → Transfer accounts → Export accounts.
5. Confirm your identity if prompted.
6. Select the accounts you want to transfer, then tap Next.
7. A QR code appears on your old phone. Scan it with your new phone.
8. Confirm the transfer is complete.

If you are moving more than a handful of accounts, the app may generate multiple QR codes. Scan each one in sequence.

Steps to Manually Transfer on iPhone (iOS)

1. On your new iPhone, install Google Authenticator and tap Get Started.
2. Tap Scan a QR code when prompted.
3. On your old iPhone, open Google Authenticator.
4. Tap the three dots (bottom right) → Transfer accounts → Export accounts.
5. Confirm your identity if prompted.
6. Select the accounts to transfer, tap Next, and a QR code will appear.
7. Scan it using your new iPhone.

If the QR Code Does Not Scan

A few things that typically fix this:

• Increase screen brightness on the old phone
• Move to a well-lit area
• Hold the new phone steady at a consistent distance (roughly 20–30 cm)
• If scanning still fails, look for the option to enter a setup key manually inside the app

What to Do If You No Longer Have Your Old Device

This is the scenario all three major competitors largely skip over. If your phone is lost, broken, or unavailable, your options depend on whether you had sync enabled.

If Your Codes Were Synced to Google Account

Sign into your Google Account on your new device inside the Authenticator app. Your codes will restore automatically. This is exactly why enabling sync beforehand matters.

If Your Codes Were Not Synced — Use Backup Codes

Google provides backup codes for your Google Account that can be used when Authenticator is unavailable. To find them:

1. Go to your Google Account and select Security.
2. Under "How you sign in to Google," select 2-Step Verification.
3. Scroll to Backup Codes and click Show Codes.

Each code is single-use. Once you have used all 10, you can generate a new set by clicking Get New Codes. Teams managing shared accounts commonly report that these codes are the fastest recovery path when a device is suddenly unavailable.

For Non-Google Third-Party Accounts

If you used Authenticator with Facebook, a banking app, or any other service and did not have sync enabled, you will need to contact each service directly to reset or disable 2FA. There is no shortcut here — without the original codes or a backup, account recovery falls on the service provider's process.

How to Transfer Google Authenticator to a Different Google Account

This is a real but underserved question. If you want to move your Authenticator codes from one Google Account to another — say, from an old personal account to a new primary one — the process works like this:

1. Open Google Authenticator on your phone.
2. Tap your profile picture (top right).
3. Select Use Authenticator without an account. This unlinks your codes from the current Google Account and stores them locally on the device.
4. Tap the profile icon again (now showing as a person icon).
5. Select the Google Account you want to link to, or sign in to a new one.
6. When prompted to save codes to this account, tap Allow.

Your codes are now linked to the new Google Account and will sync to any device where you sign in with that account going forward.

How to Back Up Google Authenticator

Transferring once is not enough. Setting up a backup means you are not starting from scratch the next time you switch phones.

Enable Google Account Sync as an Ongoing Backup

This is the simplest and most reliable option. Once sync is active, codes are backed up automatically every time a change is made. No manual steps required going forward.

Save Your Google Backup Codes

As described above, Google provides 10 single-use backup codes through your account's Security settings. Keep these somewhere offline — a printed note stored securely, or an encrypted password manager. Storing them in your email is not ideal; if your account is compromised, so are the codes.

A Note on Screenshot Backups

Some guides suggest taking a screenshot of the QR code generated during export and saving it as a backup. This works in theory, but carries a real security risk. If that screenshot ends up in a cloud photo backup — which it often does automatically — anyone who gains access to your photo library can use it to add your accounts to their own Authenticator app. If you choose this route, store the image offline only, and treat it like a password.

After the Transfer — Recommended Security Steps

Once the transfer is done, a few steps are worth taking before you move on.

Test One Code First

Before deleting anything from your old device, generate a code on your new phone and use it to log into one of your accounts. Confirm it works. Only then clean up.

Enable Privacy Screen

Google Authenticator has a Privacy Screen setting that requires biometric verification (Face ID, fingerprint) before the app can be opened. It adds a meaningful layer of protection, especially if your phone is shared or lost.

To enable it: open the app → Menu → Settings → Privacy Screen → toggle on.

Remove Codes from Your Old Device

If your old phone is being sold, given away, or decommissioned, delete your Authenticator codes from it. You can swipe to delete individual codes, or remove the Google Authenticator service entirely from your Google Account settings. Note: removing the service deletes codes from your Google Account but does not delete your entire Google Account.

Troubleshooting Common Transfer Issues

Codes Not Appearing After Sync

• Confirm you signed into the correct Google Account
• Check your internet connection
• Make sure the app is updated to the minimum required version
• Sign out and back in if codes still do not appear

Codes Showing as Invalid After Transfer

This is almost always a time sync issue. From version 7.0 onward, Google Authenticator uses the time setting from your device's operating system rather than an in-app setting. Go to your phone's system settings and make sure the date and time are set to automatic. Once corrected, codes should work immediately.

Transfer Was Interrupted Mid-Process

Safe to restart. Your old device codes remain intact throughout the process and are not removed until you manually delete them. Start the export again from the beginning.

Conclusion

Two methods handle Google Authenticator transfers: Google Account sync (fast, cross-platform, no old device needed) and manual QR export (works for all accounts, requires both phones). Enable sync now to avoid complications next time you switch devices.

Frequently Asked Questions

Do I need both phones to transfer Google Authenticator?

Only for the manual QR export method. If your codes are synced to your Google Account, you only need your new phone — sign in and codes restore automatically.

Will my old phone's codes be deleted after transferring?

No. Neither transfer method removes codes from the old device. You need to delete them manually once you have confirmed the new device is working correctly.

Can I transfer Google Authenticator from Android to iPhone?

Not via QR export — that method only works within the same platform. Use Google Account sync instead, which works across Android and iOS without any additional steps.

What if I lose my phone with Google Authenticator on it?

If sync was enabled, sign into your Google Account on a new device to restore codes. If not, use Google backup codes or contact each third-party service individually to reset 2FA.

Is it safe to screenshot the Google Authenticator QR code as a backup?

It works, but it carries risk. If the screenshot is automatically backed up to a cloud service and that account is compromised, someone could use that image to access your accounts. Offline storage only, treated like a password.
