Some of you probably don't know about Steam Guard, a way to protect from losing your Steam account to a scammer. It's simple to setup, which I highly recommend to you all.
While logged in on Steam site:
Click Username > Account details > Account Security > Manage Steam Guard > Pick Phone or Email.
Thereafter, you'll be sent a code whenever you login from an unrecognized device—which of course is what a scammer would use.
This is Steam's version of what's more commonly known as Two Factor Authentication, which you should have on all your important online accounts.
