[Defender Pro] two factor authentication when cellphone is replaced

I replaced my cellphone and my old data didn’t completely sync with the new phone. Google authenticator app on iphone is telling me I need to set it up… not sure how to do this. I can get access through the wpmudev hub, but can’t figure out how to reset my 2 factor authentication (google app) on my phone… says I need to scan a barcode but not sure where to find that… can you help?
