Good news for those who have had problems with their Steam accounts in the past, including myself, Steam Guard is now available to all users. This essentially adds an extra layer of protection from people trying to hack your account. To go into effect, users must make sure to verify their email address and then it should automatically start working. If anyone attempts to login to your account from any unrecognized computer, you will be sent an email with a special access code to verify if this was actually you or not.
Steam has battled with hacked accounts for years so I’m glad they are taking steps to help their users feel safer using their service. You can read up more information about Steam Guard and how you can better protect your account on their Steam support page.
