What can be accomplished with a brute-force attack?

Guess a user’s password is the correct answer. A brute force attack is an attempt to crack a password or username using a trial and error approach. In a brute-force attack, an attacker’s software tries every combination of letters, numbers, and special characters to eventually find a string that matches a user’s password.
