This method can be highly effective if the targeted user has a weak password.

To combat brute force attacks, it is crucial to enforce password complexity rules. These rules typically include a combination of uppercase and lowercase letters, numbers, and special characters.
Best Practices for Strong Passwords
- Use a minimum password length of at least 8 characters.
- Include a mix of uppercase and lowercase letters.
- Add numbers and special characters to increase complexity.
- Avoid using easily guessable personal information.
- Regularly update passwords and avoid reusing them across different accounts.
Implementing Account Lockouts
In addition to password complexity rules, implementing account lockouts can act as a deterrent against brute force attacks. With account lockouts, users are temporarily or permanently locked out of their accounts after a certain number of failed login attempts.

When implementing account lockouts, it is important to strike a balance between security and user convenience. While a stringent policy may provide higher security, it could inconvenience users with frequent lockouts. A recommended approach is to allow a certain number of failed login attempts before enabling a temporary lockout, and to notify users about the lockout and provide means of account recovery.
Protecting Against Brute Force Attacks: Additional Measures
In addition to password complexity rules and account lockouts, there are other measures that can further safeguard against brute force attacks.

Rate limiting involves restricting the number of requests a user or IP address can make within a specific time frame. By implementing rate limiting, brute force attacks become significantly less effective since the number of attempts that can be made per minute or hour is limited.
Implementing CAPTCHA
Utilizing CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) can effectively thwart brute force attacks. By requiring users to prove they are human by solving a challenge, such as identifying distorted letters or selecting specific images, automated password guessing attempts are prevented.
