It's recommended that you change the default username for your WordPress site to a username that is only specific to you.

To change the username, go to "Users" on your dashboard and create a unique username and password.

Remember to set the user role to administrator and delete the previous default admin user profile.

You can significantly reduce the chances of bots breaking into your website by limiting the number of login attempts made from the same IP address.

To limit login attempts, you can install a plugin that will lock out any IP address from your WordPress site if there are more than x number of failed login attempts.

You can also use the built-in security features that come with WordPress, such as Captcha and Challenge Questions. Some website hosts may also have built-in features that limit login attempts.

You can change the default login URL on your website by adding a string to the end of it. This will make it impossible for bots to break into your website by guessing the URL.

For example, you can change it to "yourdomainname" .com/login instead of "yourdomainname" .com/wp-login.PHP.

SSL certificates verify the identity of the user to the website, as well as assure confidentiality between a visitor's browser and the website.

Once you set up SSL/ HTTPS, only the user's browser can decipher data sent from a server as the data is already encrypted.

Two Factor Authentication involves adding a second layer of security to help protect your WordPress login from being hacked.

It involves generating a code on a trusted device that acts as a second password. Upon logging in on your WordPress with your username and password, the login page prompts for the code.

To do this, you should install Apache or Nginx .htaccess files. These are codes that will stop anyone without permission from accessing your site.

While this may be relatively complex to implement compared to other methods, you create an extra security layer for your WordPress.
