Switch Google Authenticator to Another Phone: Complete Guide

When upgrading your mobile device or replacing an old phone, transferring Google Authenticator to a new phone is an important step to ensure you do not lose access to accounts protected by two-factor authentication. This guide will explain two effective methods to complete this process safely.

There are two main ways to transfer Google Authenticator: using a QR code generated from the old device, or manually entering the recovery key. The first method is faster and recommended if both devices are available, while the second method is useful when you do not have access to the old device.

Method 1: Transfer via QR Code

This is the quickest way to transfer Google Authenticator to another phone when you still have the old device.

On your old mobile device:

1. Open the Google Authenticator app
2. Tap the three-dot menu icon in the top right corner
3. Select “Transfer Accounts” from the menu
4. Tap “Export Accounts” and confirm with your PIN
5. Select the accounts you want to transfer to the new device, then tap “Next”
6. The app will display a unique QR code

On your new mobile device:

First, ensure Google Authenticator is installed and launched.

1. Open Google Authenticator
2. Tap the three-dot menu icon in the top right corner
3. Select “Transfer Accounts” from the list
4. Tap “Import Accounts”
5. Choose “Scan QR code” from the available options
6. Use your device’s camera to scan the QR code from the old device
7. The transfer process will complete automatically

Method 2: Recovery Using the Backup Key

If you do not have access to the old device or encounter issues scanning the QR code, use the recovery key (also called the secret key). This method works on any device as long as you have the recovery key.

1. Download and open Google Authenticator on the new device
2. Tap the plus (+) icon in the bottom right corner
3. Select “Enter a setup key” instead of scanning a QR code
4. Find and enter the recovery key into the “Key” field
5. In the “Account” field, add a note for easy identification (e.g., “Gate.io Email” or “Bank Account”)
6. Tap “Add” to complete

Important Tips When Transferring Authenticator

Before starting the transfer process, you should store the recovery key securely. This key allows you to regain access to Authenticator even if both devices are lost.

If the generated verification codes do not work after the transfer, ensure that the time is synchronized on both devices. Go to device settings, select “Date & Time,” and enable “Automatic date & time” to sync with the time server.

You can also add notes for each account within Authenticator to easily identify them when managing multiple codes protected by Google Authenticator. This is especially helpful if you manage multiple platforms or services.

By following these instructions, you will successfully transfer Google Authenticator to a new phone without risking losing access to your accounts.
