Google Authenticator Review 2026: Simple, Now With Sync
Google Authenticator is the simplest reliable authenticator for most people, and its old weakness — codes trapped on one phone — is fixed: you can now sync codes to your Google Account, or keep them only on the device and move them with an export QR code. It remains deliberately basic: no desktop app and few extras. Choose it if you want a free, no-fuss app; choose something else if you want app-level PIN protection or codes on a computer. Details below are from Google's help pages, checked on 16 October 2026.
Two ways to use it
| Signed in to a Google Account | "Use without an account" | |
|---|---|---|
| Where codes live | Saved in your Google Account and synced across your devices | Only on this device |
| New phone | Sign in and "your codes are automatically synced to this device" | Export from the old phone, import on the new one by QR code |
| Protection | Google says it encrypts Authenticator codes in transit and at rest | Depends on your device's own lock and encryption |
| Risk to watch | Your Google Account becomes the key to your codes — protect it with strong 2FA | Lose the phone without an export and the codes are gone |
Google's help page lists Android 6.0 or above, and iOS 4.0 or above for syncing.
Moving to a new phone: the exact steps
With sync: install the app on the new phone, sign in to the same Google Account, and check that every code appears before you wipe the old phone. Without sync: on the old phone open Menu → Transfer codes → Export codes; on the new phone open Menu → Transfer codes → Import codes and scan the QR code shown on the old device. Then test one code on each important account. More detail is in moving 2FA to a new phone.
Strengths
It is free, simple and familiar; services that offer authenticator-app 2FA work with it via the standard QR code. The choice between synced and device-only storage is now yours, which is a genuine improvement.
Weaknesses
There is no desktop app. If you choose sync, the security of every code rests on your Google Account, so that account itself needs strong protection — ideally a passkey or security key. And it has few extras compared with rivals such as Microsoft Authenticator or a password manager that stores codes.
Alternatives
Compare Authy vs Google Authenticator, the Microsoft Authenticator review, or storing codes in a password manager such as Proton Pass. Our best 2FA apps guide ranks the options.
Frequently asked questions
Does Google Authenticator back up codes?
Yes, if you sign in: codes are saved in your Google Account and synced across your devices. If you choose "Use without an account", codes stay only on that device.
How do I move Google Authenticator to a new phone?
Sign in to the same Google Account on the new phone, or use Menu → Transfer codes → Export codes on the old phone and Import codes on the new one to scan the QR code.
Can I use Google Authenticator without a Google Account?
Yes. Choose "Use without an account" on first launch; your codes then stay on the device and are not available on other devices.
Is Google Authenticator safe?
Google says it encrypts codes in transit and at rest. If you use sync, protect your Google Account strongly, because it now guards your codes.
