This means that someone hacked your password, and you need to prove that you are the account’s real owner. I am always saying to my friends how important it is to make a strong password on your account. If you can’t invent one hard password, then use a strong password generator. It will surely help you. It creates random passwords that no one can ever hack. We use passwords every day to access email accounts, bank accounts, Facebook and Twitter accounts, and hundreds of other services, and there we have a lot of personal information.
