1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsTo avoid losing access when you change or lose a phone, protect two different things: the authenticator credentials that generate your codes, and the one-time recovery codes issued by each account provider. Set up the authenticator on your replacement device, save each service’s recovery codes separately, and test your sign-in options before wiping the old phone. The exact steps depend on your authenticator app, device type, and account.
Authenticator codes and backup codes are not the same
An authenticator app generates rotating verification codes using credentials enrolled for each account. Transferring or syncing those credentials lets the app generate codes on another device.
A service-issued backup code is different: it is a one-time alternative sign-in method provided by a particular website or account provider. It can help when your phone or authenticator is unavailable. It does not restore the authenticator app or transfer its credentials.
Prepare before changing phones
- Inventory your accounts and fallbacks. For each important service, note which authenticator is enrolled and whether you have recovery codes, a passkey, a trusted device, a registered phone number, or a security key. Google lists several alternate sign-in routes, but options vary by provider. Google’s 2-Step Verification help explains its available methods.
- Create or refresh each service’s recovery codes while signed in. For a Google Account, open the account’s 2-Step Verification settings and choose backup codes. Google provides a set of ten 8-digit codes; each works once. Creating a new set deactivates the previous one. Download or print the codes and store them securely. Google says, “Do not share your backup codes with anyone. Google never asks for a backup code other than at sign in.” See Google’s instructions for signing in with backup codes.
- Choose and complete the authenticator’s transfer method. Follow the app-specific procedure below while the old phone still works. Do not assume an app’s cloud sync includes every account type.
- Test before erasing the old phone. On the replacement, confirm that the expected accounts appear and that a generated code is accepted. Also confirm you can reach your recovery codes and at least one other enrolled fallback. Then, and only then, erase or trade in the old device.
How do I transfer Google Authenticator codes to a new phone?
Google Authenticator offers account synchronization and direct export. The synchronization instructions require Google Authenticator version 6.0 or higher on Android, or version 4.0 or higher on iOS, according to Google’s current help page.

Sync through a Google Account
If your codes are synced, install Google Authenticator on the new device and sign in to the same Google Account. Check that the expected accounts are present. Google says it encrypts Authenticator codes “both in transit and at rest across our products.” That is Google’s description of its protection, not an independent security evaluation. Your ability to restore this way depends on being able to access the Google Account used for sync, so make sure that account has working recovery methods.
Transfer directly from the old device
While you still have the old phone, use Google Authenticator’s export option to display QR code(s), then scan them with the app on the new phone. If you use Authenticator without a Google Account, codes remain on that device, so complete this manual transfer before retiring it. Treat the export QR as sensitive: it contains credentials used to generate sign-in codes. Do not share it or photograph it casually, and keep it out of view while transferring. See Google Authenticator’s transfer and verification-code instructions.

How do I restore Microsoft Authenticator?
Microsoft’s backup and restore works only between devices of the same type; it is not a cross-platform move between Android and iOS. Microsoft personal accounts and third-party one-time-password accounts may restore their codes. Work or school entries restore only their account names, so you must sign in again. Organization policy may require help from an administrator or help desk.
Microsoft’s current support page says Android backup is expected to move to Google One beginning in January 2027. If you are migrating after that date, check Microsoft’s live backup instructions for the current process. Any cloud restore also depends on access to the account used for backup.

Which recovery method should you rely on?
| Method | Useful when | Important limitation |
|---|---|---|
| Authenticator account sync | The app supports sync and you can access its cloud account on the new phone. | Access to the sync account becomes part of recovery; confirm the right account is signed in. |
| Direct app transfer | The old phone is still available. | Complete export and import before losing or erasing the old device. The transfer QR contains sensitive credentials. |
| Service-issued backup codes | The phone or authenticator is unavailable. | Codes may be single-use. Protect the current set and replace it if lost or exposed. |
| Spare security key | The service accepts a separately enrolled hardware key. | Enroll and test the key in advance; an unregistered key cannot recover the account. |
| Provider account recovery | Other sign-in methods are unavailable. | Recovery may take time or require provider-specific checks; it is not a replacement for preparing fallbacks. |
Choose based on whether the old device is available, where the backup is stored, whether the method works across your devices and account types, and whether you enrolled it before the loss. A cloud copy is not an independent fallback if you cannot regain access to the account that holds it.
What should I do if I lose my phone?
- Try an enrolled alternative. Depending on the account, this may be another signed-in phone, a registered number, a saved backup code, a hardware security key, or a passkey on another device. Google lists these routes and directs users to account recovery if they cannot sign in another way.
- Secure the lost device and account. Google advises signing out of the lost device and changing the account password. If your Google Authenticator codes were synced, Google also describes removing the device or remotely erasing it.
- Re-enroll where codes were not synced. If the lost phone held the only copy of an authenticator credential, you may need to use each service’s recovery process and enroll a new authenticator. Start with the accounts that matter most and update their recovery methods after regaining access.
For Google’s available recovery options and lost-device guidance, see Fix common issues with 2-Step Verification. Providers differ, and work or school accounts may require administrator assistance.

Where should I keep recovery codes?
Store service-issued recovery codes somewhere secure and accessible without the phone they are meant to replace—for example, in a protected password manager or a securely stored printed copy. Keep them private, and replace a set if it is lost or exposed. For Google, generating a fresh set invalidates the previous one. Do not store the only copy somewhere that depends on the same account or device you may need to recover.
