BEWARE: App updates may erase your codes
My authenticator app was just updated, and in the process all my codes were erased. MANY others have apparently also had this problem. There seems to be no way of getting them back (they are erased from my account, not from my device), which means i can only hope that the sites where i have an account with 2FA will somehow allow me to access my account without 2FA. Good thing i don’t happen to have thousands of moneys on my coinbase account for example, then i would be seriously worried.
