For security reasons, close your web browser when you are done accessing services that require authentication!
Be wary of any program or web page that asks you for your World of Warcraft account name and password. Secure World of Warcraft web pages that ask you for your account name and password will generally have URLs that begin with "https://www.wow-europe.com" or "https://www.worldofwarcraft.com". In addition, your browser should visually indicate that you are accessing a secure page.
Ahi queda eso.
