You will also be notified if any login attempts from computers other than those you've authorized occur. A special access code will be sent to your contact email address, and this code must be entered into Steam before your first login on an unfamiliar computer is complete. With Steam Guard enabled, anyone attempting to login as you from an unrecognized computer must first provide additional, one-time authorization. As a Steam account holder, you can now take advantage of this additional level of account security, further prohibiting others from gaining access to your account.Īs a beta participant, once you've verified your email address with Steam, Steam Guard becomes available for your use and is enabled for your Steam account by default.
