To transfer your Google Authenticator accounts to a new device, you'll need to export the accounts from your old device and import them into your new device. 

This is typically done by scanning a QR code generated on the old device with the Authenticator app on the new device.

Here's a step-by-step guide:

1. On your Old Device (the device with the Authenticator app):

• Open the Google Authenticator app.
  
• Tap the menu icon (usually three dots or a gear icon).
  
• Select "Transfer accounts" or "Export accounts".
  
Follow the prompts to unlock your device and choose the accounts you want to transfer.

Tap "Next" or "Export".

A QR code will be displayed on your screen.

2. On your New Device (the device where you want to transfer the accounts):

Install and open the Google Authenticator app.

If prompted, select "Get Started" and then "Import existing accounts?" or "Add accounts".

Choose "Scan QR code".

Scan the QR code displayed on your old device.

If the transfer is successful, the accounts will be added to your new device.
