Few things help protect people’s account better than two-factor authentication, and the easier it is, the more people will use it. While two-factor authentication has been available on Steam for some time, in the form of Steam Guard, users still had to use a code sent to them via email, which can be somewhat inconvenient at times. Fortunately, Valve is currently testing two-factor authentication within its mobile app that will make things much easier for users and therefore make them more likely to use these extra protections.
