Which is a benefit of using account lockout policies?

Implementing account lockout policies is critically important in user account management as it serves a primary security function: preventing repeated login attempts from attackers. When an account lockout policy is in place, it temporarily disables a user’s account after a certain number of failed login attempts within a designated timeframe. This mechanism is aimed at thwarting brute-force attacks, where an attacker systematically tries different password combinations to gain unauthorized access to an account. By locking the account after a few failed attempts, the system not only increases security but also acts as a deterrent for potential intruders, effectively making it more difficult for them to succeed in their attempts to breach accounts.

In contrast, other options don’t align with the core purpose of account lockout policies. For instance, allowing users to reset passwords easily is more related to user convenience rather than security; immediate access for all users does not support safety measures; and simply reducing the number of accounts does not pertain to the functioning of account lockout policies. Hence, the key benefit is indeed the prevention of repeated login attempts from attackers, reinforcing the stability and security of the user accounts in the system.
