restoring codes on the same device - backup
I had setup authenticator on my phone and added some personal and work accounts .. my phone got a virus and I had to reset it.. after restoring the apps on the same device, it appeared to me I hadn't backed up my authenticator on any email or at least i didn't back it up on my personal email so I am not sure where the codes went... I lost access to the codes.. now I am having a hard time logging to some of these accounts.. particularly my personal facebook account and I got logged out of facebook on all devices and the only way to login is with the code!! I have setup the app on the same device now and backed it up on my personal email. Please help me restore the codes.
