Steam Guard is a two-factor authentication of the Steam platform.
It allows requiring not only a password when logging into an account from an unfamiliar device, but also an additional code that is sent to an email or generated in the mobile app.
The codes are updated every 30 seconds, so it's impossible to predict them. In addition, they are one-time use — once you have logged in to your account with this key, no one else will be able to use it.

1. Go to the Steam platform official website and log in, if necessary.
2. In the upper right corner, click on the account name to open the list of features.
