How can I transfer my Google Authenticator MFA setup to a new phone?

The easiest way to transfer your Google Authenticator MFA setup to a new phone is by using the 'Transfer accounts' feature within the app itself. Go to Settings > Transfer accounts, choose 'Export accounts,' scan the QR codes generated on your old phone with your new phone, and then confirm the transfer on both devices. If this feature isn't available or successful, you'll need to re-add each account by scanning the QR code or entering the secret key provided by each service.
