My account was hacked and am unable to recover it; whoever hacked it put a 2 verification system in place. I can request a new password and it's sent to my email but after entering it I'm asked for the second step verification which I don't know. I've searched the web for FB technical support but no luck; ordinarily I wouldn't care but there are a lot of memories and photos I want to recover of family, friends and pets. Any advice/help? Thank You in advance?
