The significance of "User Account Lockout" in Salesforce primarily centers around enhancing security measures to protect against unauthorized access. When a user exceeds the allowed number of failed login attempts, the account becomes temporarily locked. This mechanism serves as a crucial safeguard against brute force attacks, where an attacker systematically attempts to guess a user's password. By locking the account after a specified threshold of unsuccessful login attempts, Salesforce helps to ensure that malicious actors are unable to gain access to sensitive information or perform unauthorized actions within the platform.

While disabling user notifications, enforcing password complexity, and limiting the number of administrators are important aspects of user management and security, they do not directly pertain to the primary function of user account lockout, which is focused specifically on preventing unauthorized access following repeated login failures. Thus, the emphasis on preventing unauthorized access through account lockout is what makes this response the correct choice.
