“Enable Two-Factor Authentication”
Another excellent way to protect your WordPress site from brute force attacks is by enabling two-factor authentication. Aside from entering your password, this type of authentication would require you to confirm your identity via an authorization code sent to your registered mobile number.
This may be tedious and inconvenient at times but given the security, it offers to your website, you will surely not mind confirming your identity over and over again every time you log in to your site. To enable two-factor authentication, you will need to install plugins (e.g. Duo Two-Factor Authentication, Clef, and Google Authenticator) that add this special security feature.

“Keep WordPress Core, Theme and Plugins Up-To-Date”
One thing that a WordPress programmer would suggest to keep your site’s security protected is to always update your WordPress core, themes, and plugins to the latest version. You will know when there will be a new update for the themes and plugins installed on your site because WordPress will confront you with the “Update Available” banner whenever you log in to your dashboard. You just have to click on it to install the update. If you are worried that it might mess up with your site, you can always save a backup before installing the updates. If you need WordPress customization to strengthen the security of your site, then do so.
