Authenticator keychain/app

I know its been asked before but I really do think Authenticators like they have in blizzard games or even have the option that if you're using the LoL Friends app It can be used to Authenticate your account every time you log in. I want it not to be necessary but if you chose to use this method as a extra layer of security for your account. Lets say you manage to break your phone or your authenticator key chain gets lost then Riot games gets to do the old method of recovering your account through various IP checks/questions having them remove this authenticator from your account until you choose to get a new one or leave it without one. I am just concern about account security since just noticed i spent so much $$ as have many im sure. thanks for reading sorry if my grammar is awful.
