Steam Guard can help keep your Steam account secure. However, the basic email-based code provisioning system isn’t as secure as it could be. If someone steals your Steam credentials, there’s a chance they could compromise your email.

That’s where the Steam Guard mobile authenticator comes in. It adds an extra layer of security to protect your digital library, virtual items, and online reputation.

Steam Guard is a two-factor authentication feature of Steam. It provides an extra level of security on top of your username and password. With this feature enabled, Steam Guard will prompt you for a one-time code every time you log in to Steam on a new device.

While Steam Guard may seem like an unnecessary inconvenience, it keeps your account safe. Because you are the only one with access to the temporary codes generated by Steam Guard, no one can steal your account. Even if they get your password, they won’t be able to log in.
