Someone tried to access my Facebook account from an unknown device and because of this Facebook locked my account until I was able to do further security measures. When I tried to do this it asked for my password to log in which was fine but secondary asked for a code from the Facebook code generator which I am unable to get because I can't log in to facebook. I have tried alleyways they suggest to log in but all still ask for the code from the generator. How can I access this if I am completely locked out of my account.
Any help would be much appreciated.
