Olá o que você precisa fazer é qualquer contacto ou válvula goto esqueceu a senha e escolher um método para obter uma nova.

Dont panic its likely you accidently entered your details on a fake steam community website, if possible search you internet history and find the site and report it. You will be easily able to get your account back by contacting steam support and giving them some proof that the account is yours etc and they will guide you through the rest.

Here is a link to the steam support website and the article on reclaiming a hijacked steam account: support.steampowered.com/kb_article.php?...p;ref=2347-QDFN-4366

Good luck man but im sure youll get it back in no time
