Moving Google Authenticator to a new phone is much easier than it used to be. If your Authenticator codes are saved to your Google Account, signing in to that same account on the new device can sync the codes automatically.
The most important part of how to set up Google Authenticator on new phone is confirming how your codes are currently stored before wiping, selling, or resetting the old device.
1. How to Set Up Google Authenticator on New Phone
There are two main ways to move Authenticator codes: sign in and let Google sync them, or manually transfer them with QR codes.
Which method you should use depends on whether your existing codes are saved to your Google Account.
Sign In and Sync Authenticator Codes Automatically
This is the simplest method when your codes are already synced.
Install the latest Google Authenticator app on the new phone, open it, and sign in to the same Google Account you used with Authenticator on the old device.
When you sign in to your Google Account within Authenticator on a new device, saved codes are automatically synced to that device.
This automatic-sync option makes setting up Google Authenticator on a new phone much easier because you do not need to recreate every two-step verification entry individually.
Google Authenticator can also sync codes associated with multiple Google Accounts. If you use more than one Google Account, you can add another account from the profile menu and allow Authenticator to save codes to it.
Transfer Codes Manually With a QR Code
Manual transfer is useful if you use Authenticator without signing in to a Google Account or prefer to keep your codes stored locally.
- On the old phone, open Google Authenticator and go to Menu > Transfer accounts > Export accounts.
- Unlock the device when prompted, select the accounts you want to transfer, and tap Next.
- Google may generate more than one QR code if you are transferring many accounts.
On the new phone, install Google Authenticator and open Menu > Transfer accounts > Import accounts. Choose Scan QR code, then scan the code displayed on the old device. Google confirms the transfer after the QR code is successfully imported.
For how to set up Google Authenticator on new phone without cloud syncing, this QR method is the official direct-transfer option.
2. What to Do If You No Longer Have the Old Phone?
Losing the old device changes the process.
If your Authenticator codes were synced to your Google Account, install Authenticator on the new device and sign in to that account. The synced codes should become available automatically.
If the codes were stored only on the old phone and were never synced, you need to visit each website or service where Authenticator was configured, remove the old Authenticator setup, and link the new device.
For your Google Account itself, alternative recovery methods may help. Google lists options including another phone number already added to 2-Step Verification, a hardware security key, backup codes, Google prompts, or a previously trusted device.
This is why how to set up Google Authenticator on new phone is easiest when you prepare before changing devices. Syncing codes and keeping another verification method can prevent a phone replacement from becoming an account-lockout problem.

3. Common Google Authenticator Transfer Problems
One common problem is that codes do not appear after signing in.
- First, confirm that you signed in to the same Google Account that stored the Authenticator codes.
- If you previously selected Use Authenticator without an account, those codes may have remained only on the device instead of being available for automatic sync.
Another problem occurs when an imported code appears but is rejected by the website.
- Google recommends checking that the correct code is being used for the correct service.
- Time-related issues can also affect time-based verification codes, so make sure the phone’s date and time settings are accurate.
If how to set up Google Authenticator on new phone seems incomplete because only some entries transferred, repeat the export process and check whether the old device generated several QR codes. Multiple accounts can require more than one transfer code.
4. How to Protect Google Authenticator on the New Phone
After the transfer works, secure the new device before removing the old one.
- Sync Authenticator codes to your Google Account if you want them available across devices and enroll in additional 2-Step Verification methods so you are less likely to become locked out. Google also recommends considering passkeys as another sign-in method.
- Authenticator includes a Privacy Screen option that requires device authentication before the app can be opened. On Android, this can use a PIN, pattern, or biometric prompt; on iPhone, it can use device biometrics such as Face ID or Touch ID.
- Keep backup verification options somewhere secure and separate from the phone. If the device is lost later, those alternatives can make recovery much easier.
