How do I transfer OTPs to a new Device?
Google Authenticator, by default, does not sync your OTPs (One Time Passwords) across to new devices. Instead, the OTPs are tied to the specific device they were registered with.
This means, that if you were to purchase a new smartphone, that the Google Authenticator App will transfer over to the device, but the OTPs will not.
Google provides the ability to export your OTPs to facilitate transfer to new devices.
Note that these instructions are only for when you have access to both your old device and new device, assume you have your new device ready with your apps transferred over, and HAVE NOT wiped your old device.
For more information on how to transfer your apps, see your local network carrier for help.
Step 1
On your old device, select the Menu Icon (☰) in the top left hand corner. Select the "Transfer Accounts" setting.
It will open a new screen, allowing you to choose the option to Export or Import accounts.
Select "Export Accounts". You may be prompted for your fingerprint, face ID, or PIN number for your phone for security purposes. Enter in the desired method.
By default, the App will select all your OTPs for transfer. If, for any reason, there are codes you do not wish to transfer, simply de-select the check mark next to that name. When finished, select "Next".
Depending upon the amount of OTPs you have to transfer, there may be one or more QR Codes for you to scan. Once you reach this step, move on to Step 2.
Step 2
On your new device, open the Google Authenticator application. As in Step 1, select the Menu Icon (☰) in the top left hand corner, and select "Transfer Accounts".
Select "Import Accounts". It will give you brief instructions similar to described in Step 1. Select the "Scan QR code" button in the bottom right hand corner.
Scan the QR Code(s) as prompted, clicking "Next" on your old device as needed if there are multiple QR Codes.
Step 3
Verify that the codes on both devices match, and they are generating the same set of codes for each entry.
Once you have verified that the codes have come over, it is safe to wipe or factory reset your old device and dispose of it in an appropriate manner.
