Transferring MFA from an old iPhone to a new iPhone requires that the app, Google Authenticator, be installed on both phones at the same time. Connection to the network and internet is also required.
Do *not* delete Google authenticator from the old phone until you have confirmed the MFA codes have transferred.
Before transferring MFA codes between iPhones, please be sure to run the following to avoid potential issues.
- Using the App Store, download the Google Authenticator to the new iPhone. This is a free app that only requires an Apple Id to download. Note: if you restored your information from the old phone to the new phone, the app is probably already downloaded.
- Update both iPhones to the latest iOS available. Your organization may limit what iOS you can use. In this case, ensure it is on the latest version your organization uses.
- Check both phone’s App Stores for software updates. If Google Authenticator needs an update on either phone, complete the update first.
