This is the help I received from G suites help
- To delete existing Google Authenticator entries, press and hold the 6-digit code displayed on the corresponding line in the Google Authenticator App. A bar should appear with a trash can icon. Tap it to delete the entry.
- It's possible to have an unlimited number of devices providing authentication codes for the same accounts. When setting up an app to use Google Authenticator you'll be provided with either a QR code, or a string of characters. Sometimes you'll have the option of seeing both. On each device you want to have codes generated on, open the Google Authenticator app, click the + sign, and either take a picture of the QR code, or enter the string of characters - you'll also have an option to name the entry.
- You now have two devices generating codes for the same app. Now go back to the app you were adding Google Authenticator to. You'll be asked to enter a backup code from one of your devices to confirm Google Authentication. This is to ensure you've setup a device properly before activating two-factor-authentication. Simply enter one of the 6 digit codes from either device.
