How can I protect login pages from brute-force attacks?

Asked on Sep 25, 2025

Answer

To protect login pages from brute-force attacks, implement rate limiting and account lockout mechanisms, and consider using CAPTCHA or multi-factor authentication (MFA).

<!-- BEGIN COPY / PASTE -->
    # Example of a rate limiting configuration using Nginx
    http {
      limit_req_zone $binary_remote_addr zone=one:10m rate=1r/s;
      
      server {
        location /login {
          limit_req zone=one burst=5;
          # Other configurations
        }
      }
    }
    <!-- END COPY / PASTE -->

Additional Comment:

Rate limiting helps to slow down repeated login attempts from the same IP address.
Account lockout after a number of failed attempts can prevent automated attacks but should be used carefully to avoid denial-of-service risks.
Implementing CAPTCHA can help differentiate between human users and bots.
Multi-factor authentication adds an extra layer of security, making it harder for attackers to gain unauthorized access.
