How to Use Google Authenticator Transfer to Move Codes to a New Phone

Switching phones and worried about losing access to your accounts? Here's how to use Google Authenticator transfer: sign into your Google Account to sync codes automatically, or manually scan a QR code between old and new devices.

Which method applies depends on whether your codes are already linked to a Google Account.

How to Use Google Authenticator Transfer: Two Ways to Move Your Codes

There isn't just one path here, and that trips people up more than it should. Google Authenticator generates time-based one-time passwords for two-factor authentication, according to Wikipedia, and moving those codes to a new phone comes down to two distinct methods that behave differently depending on your setup.

Method 1 — Automatic Sync via Google Account

If your Authenticator app is already signed into a Google Account, this is the easier route. Install Authenticator on the new phone, sign in with the same Google Account, and your codes appear automatically. No QR scanning, no old device required at that moment.

Method 2 — Manual Export and Import via QR Code

If you're using Authenticator without a Google Account meaning your codes live only on the device itself you'll need both phones in hand.

The old phone generates a QR code, and the new phone scans it. This is the method most people picture when they think of "transferring" Authenticator, and it's also where most confusion happens.

How to Check if Your Codes Are Already Synced

Before doing anything else, it's worth confirming which situation you're actually in.

How to Use Google Authenticator Transfer: What the Cloud Icon Next to Your Profile Means

Open the app and look at the top right corner. A cloud icon with a checkmark next to your profile picture means your codes are synced to a Google Account.

A crossed-out or gray cloud icon means they're not, and you'll need the manual method instead. This one detail saves a lot of unnecessary QR scanning.

How to Manually Transfer Codes to a New Device

Manual transfer follows roughly the same logic on both major platforms, though the menu wording differs slightly.

Steps on Android

Install Google Authenticator on the new phone.
Tap Get Started, then choose Scan a QR code.
On the old phone, open Authenticator and tap the menu icon.
Select Transfer accounts, then Export accounts.
Confirm your identity if prompted (usually a fingerprint, face unlock, or device PIN).
Choose which accounts to include, then tap Next.
A QR code appears scan it using the new phone.

Steps on iOS/iPhone

Install Google Authenticator on the new iPhone.
Tap Get Started, then Scan a QR code.
On the old iPhone, open the menu and select Transfer accounts, then Export accounts.
Confirm your identity if asked.
Deselect any accounts you don't want moved, then tap Next.
Scan the resulting QR code with the new iPhone.

Transferring Between Different Platforms (Android to iPhone or iPhone to Android)

Here's something competitors rarely spell out clearly: the export/import process isn't platform-locked.

A QR code exported from an Android device can be scanned by an iPhone running Authenticator, and vice versa, because both versions of the app read the same QR format. The steps are functionally identical export on the old OS, scan with the new one.

What to Do if Your Old and New Phones Use Different Operating Systems

Just make sure both apps are updated to their latest version before starting. Older app versions occasionally use a slightly different export format, and mismatched versions are a common, avoidable reason a scan fails.

What Happens to Your Old Device's Codes After Transfer

This is one of the more common points of confusion, and understandably so.

Manual Export vs. Sync — Are Codes Copied or Removed?

Manual export and import copies the codes to the new device. It does not remove them from the old one. Your old phone keeps working with those same codes until you manually delete them or reset the device.

Sync behaves differently once you're signed into a Google Account on a new device, that account becomes the active source, and disconnecting sync on one device can affect what's stored centrally.

Before this sync option existed, as reported by TechCrunch, codes were stored only on the single device that generated them, so losing that device without a backup meant losing access outright.

In practice, most people don't notice this distinction until they're troubleshooting a "why do I have two working codes" situation.

How to Transfer Codes Without Access to Your Old Device

Not everyone has both phones in hand. Lost, broken, or stolen devices are a real and common reason people search for this exact process.

Using Backup Codes

If you generated backup codes when you first set up 2-Step Verification, they still work here. Go to your Google Account's 2-Step Verification settings, find the backup codes section, and use one to sign in and re-establish authentication on the new device. Each code works once.

Using a Saved QR Code Screenshot or Setup Key

If you saved a screenshot of the original QR code, or wrote down the setup key when you first configured an account, you can use either to re-add that account manually on the new device through the app's "add account" option.

What to Do if You Have No Backup and No Old Device

This is the scenario nobody wants, and it's also the one with the least clean answer. Without a synced Google Account, backup codes, or a saved QR code, the account-specific 2FA codes generally can't be recovered through Authenticator itself.

At that point, recovery depends entirely on the account and service in question — most platforms have their own account recovery process for exactly this situation, separate from Authenticator.

Sync vs. Manual Transfer: Which Method Should You Use

Both methods work. Which one fits depends less on preference and more on what you already have set up.

Comparison Table — Sync vs. Manual Export/Import

Factor	Sync (Google Account)	Manual (QR Export/Import)
Requires old device present	No	Yes
Requires Google Account sign-in	Yes	No
Codes removed from old device	No, remains linked centrally	No, stays on old device
Works across platforms (Android/iOS)	Yes	Yes
Best for	Ongoing, low-effort backup	One-time device switch

When Sync Is the Better Option

If you're likely to switch devices again, or you just don't want to think about this process a second time, syncing to a Google Account is the lower-maintenance choice.

When Manual Transfer Is Necessary

If you're intentionally avoiding linking codes to a Google Account, for privacy or account-separation reasons, manual transfer is the only route and it's a fine one, as long as you still have your old phone.

Fixing Common Problems During Transfer

Most transfer issues come down to a handful of repeat causes.

QR Code Won't Scan

Screen brightness, glare, and camera distance cause more failed scans than people expect. Increase brightness on the phone showing the QR code, and hold the scanning phone steady about six to eight inches away.

Identity Confirmation Step Explained

Before generating an export QR code, Authenticator asks you to confirm it's really you typically through your phone's existing lock method, whether that's a fingerprint, face scan, or PIN.

It's a safeguard against someone else exporting your codes if they briefly get hold of your unlocked phone.

Codes Missing or Not Appearing After Transfer

If an account doesn't show up after import, double-check it wasn't accidentally deselected during the export step. It's an easy checkbox to miss when transferring several accounts at once.

How to Set Up Google Authenticator With Multiple Google Accounts

Authenticator can hold codes for more than one Google Account on the same device. Tap your profile picture, choose Add another account, sign in to the additional account, and allow it to start saving codes.

Each account's codes stay associated with that account specifically, which matters if you ever need to sync or transfer just one of them later.

Conclusion

Google Authenticator transfer comes down to two paths: automatic sync through a Google Account, or manual QR export between two physical devices.

Which one you need depends on whether your codes are already linked to an account and whether your old phone is still accessible.

Frequently Asked Questions

Does transferring Google Authenticator delete codes from my old phone?

No. Manual export and import copies codes to the new device without removing them from the old one. You'd need to delete them manually or reset the old phone separately.

Can I transfer Google Authenticator from Android to iPhone or iPhone to Android?

Yes. The QR export/import process works across platforms as long as both apps are updated to their current versions.

What if I lost my old phone before transferring my codes?

Use backup codes generated during initial 2FA setup, or a saved QR screenshot/setup key. Without either, recovery depends on each individual account's own process.

Do I need an internet connection to transfer Authenticator codes?

Manual QR transfer doesn't require internet access. Syncing through a Google Account does, since it needs to connect to your account.

How long does it take for transferred codes to start working on the new device?

Manually transferred codes work immediately after scanning. Synced codes also appear right away once you're signed into the same Google Account.
