Brute force is one of the oldest forms of hacking, where a hacker run a script and attempt to login to your account by trying different combination from dictionary Words. WordPress users are lucky enough that there are several security plugins and other template tweaks to safeguard the blog from hacking attempts. One of them is changing the default WordPress username ‘admin‘. It makes a big difference to your site and protects you from many brute force attacks.
Another method is to limit the number of login attempts with wrong password. By default WordPress allows unlimited number of login attempts. We can use a plugin to limit the number of login attempts from the same IP. It adds a time lag for login attempts. This also prevents many brute force attacks.
