What is steam guard nedir?

Steam Guard is an additional security measure provided by Steam to protect users' accounts from unauthorized access. It requires users to enter a unique code sent to their registered email address or mobile device when logging in from a new computer or browser. This adds an extra layer of protection to prevent anyone else from gaining access to a user's account unless they have both the password and access to the registered email or mobile device. Steam Guard can be activated easily from the Steam settings and is highly recommended for all users to enhance the security of their accounts.
