It’s not constructive to answer your question instead of explain the situation to you for the 8th time. There is only one device and it was wiped and can never be recovered, not even by restoring the OS, but the Google Prompt is still the default option forever now. I found this mildly infuriating.
The best solution is to use something like Google Auth since only the SMS is being phased out. Do you understand now or de we need to repeat this again and again?
