I want to be able to add a recovery phone number to my account, so if I have enabled the two factor authentication, lost my phone and my local ssh repository, I would be able to restore it through an SMS to the recovery phone I add to my account.
I give it a critical issue, because for me it was a big issue!
I just left my old work and my local ssh repository deleted and my phone as well, good that I had an ssh repository at home so i could get the recovery codes. If I did not had two ssh repositories so I would have lost my data!!!
