Lab: 2FA bypass using a brute-force attack

EXPERT

This lab's two-factor authentication is vulnerable to brute-forcing. You have already obtained a valid username and password, but do not have access to the user's 2FA verification code. To solve the lab, brute-force the 2FA code and access Carlos's "My account" page.
