Account security is very important to us. As we have recently seen a rise in the number of compromised World of Warcraft accounts, we recommend you to take a few moments to read these tips to help protect your privacy and ensure your security.

• Verify that your email address in Account Management is current. You can see your address on the right side of the Account Management page and change it with the “Change Contact Info” button.
  
• Make sure your operating system, web browser, and other software is up-to-date with the latest patches and security updates.
  
• Scan your computer for viruses, Trojans, and key loggers.
  
• After doing this, we highly recommend changing the password on the account to a brand-new, unique one, and making sure to keep this password private.

These simple steps can go a long way in maintaining account security. If you are seeking an additional layer of security, consider purchasing the optional Blizzard Authenticator, available at the online Blizzard Store.

We hope you have a happy -- and safe -- holiday season!
