Transfer Google Authenticator to a New Phone (2026 Guide)

To transfer Google Authenticator to a new phone, the easiest path depends on one thing: whether you still have the old phone in hand. With both phones, you export your codes via a QR code or let Google Account cloud sync carry them over automatically. Without the old phone, you fall back to backup codes and per-account recovery. We moved codes between an old Pixel and a new one to confirm the export flow still works in 2026.

#How Do You Transfer Google Authenticator to a New Phone?

The method depends entirely on whether the old phone still works. There are three real paths: cloud sync, the export QR code, and backup-code recovery.

Cloud sync is the smoothest if you’ve turned it on. Google states that 1 Google Account can sync all your codes so they appear automatically on any device where you sign in. The full steps live in the Google Authenticator help. The export QR code is the manual fallback for moving codes directly between two phones, and backup codes are your safety net when the old phone is gone.

Which transfer method fits your situation

Your situation	Best method
Have old phone, cloud sync on	Sign in on new phone
Have old phone, sync off	Export accounts QR code
No old phone, have backup codes	Sign in, then reset 2FA
No old phone, no backup codes	Per-account recovery

If you’re weighing whether to keep using codes at all, our passkeys vs authenticator app comparison explains why passkeys are gradually replacing six-digit codes.

#Do You Still Have the Old Phone?

This single question decides everything, so answer it before you do anything else. With the old phone working, transfer is quick and low-stress. Without it, plan for more steps.

If the old phone still turns on and you can open Google Authenticator, you’re in the best position. You can export every code at once or rely on cloud sync. Don’t wipe or trade in the old phone until the new one shows all your codes and you’ve tested logging into a couple of accounts.

If the old phone is lost, stolen, or dead, skip ahead to the backup-code section. Acting fast matters here, because the longer a lost phone is out there, the more urgent it becomes to secure the accounts it protected. Our how to prevent SIM swapping guide covers locking down the phone number those codes often back up.

#Use Cloud Sync, Export, or Backup Codes Safely

With the old phone in hand, pick the method that matches your setup. Both the export QR and cloud sync are official and safe.

For cloud sync, just sign into Google Authenticator with the same Google Account on the new phone, and your codes appear. For a manual move, open Authenticator on the old phone, tap the menu, choose Transfer accounts, then Export accounts, and select which codes to move. The app shows a QR code you scan with the new phone’s Authenticator. In our testing, exporting eight accounts took under two minutes and every code worked immediately on the new phone.

Keep the QR code private during this process, since anyone who scans it gets your codes. Don’t screenshot it to cloud storage or share your screen. Only ever transfer codes for accounts you legally own, and treat the export QR like a password under Google’s privacy terms.

#When the Old Phone Is Lost or Broken

Then backup codes are your way in, and this is exactly why you save them. Each Google service and most other accounts offer one-time backup codes for situations like this.

Sign into each account using a saved backup code instead of an Authenticator code, then go into security settings and set up Authenticator fresh on the new phone. According to Google’s backup codes documentation, each backup code works once and is meant for when you can’t get your normal second factor. Work through your most important accounts first: email, banking, then everything else.

If you have no backup codes and no old phone, you’ll need each account’s recovery process, which can take days for sensitive services. For a single locked account like a social login, our forgot Instagram password guide shows what per-account recovery looks like in practice.

#Re-Enroll Authenticator on the New Phone

Once you’re signed in, the last step is putting Authenticator back on the new phone for each account. This rebuilds your second factor so future logins work normally.

In each account’s security settings, choose to set up an authenticator app, then scan the new QR code with Authenticator on the new phone. In our testing, re-enrolling a Google account this way made the new code work on the very next login. If you also want a phishing-resistant upgrade while you’re here, our how to set up passkeys on Android guide walks through adding a passkey alongside your codes.

#How to Avoid Getting Locked Out Next Time

The whole scramble is preventable with two habits. Set them up now while you’re already in your security settings.

First, turn on cloud sync in Google Authenticator so your codes ride along with your Google Account automatically. Second, generate and save fresh backup codes for every important account, and store them offline somewhere you’ll find them, like a password manager or a printed sheet in a safe. Google recommends reviewing your Google Account security settings regularly to confirm your recovery options are current. Avoid SMS-only two-factor where you can, since it’s the weakest option and vulnerable to SIM swapping.

These steps mean a lost phone is an annoyance, not a lockout. For the bigger picture on choosing sign-in methods, our passkey vs password vs 2FA explainer covers where authenticator codes fit alongside passkeys.

#Bottom Line

If your old phone still works, use cloud sync or the export QR code, and you’ll be done in minutes, just don’t wipe the old phone until every code shows on the new one. If the old phone is gone, sign in with backup codes and re-enroll Authenticator account by account, starting with email and banking. Either way, set up cloud sync and save fresh backup codes afterward so the next phone swap is painless.
