Last Updated: May 2, 2024

Latest News: I updated the information below.


WordPress are going in the right direction. They have decided to implement better security into the core file system. This will help fight brute force login attempts and stolen passwords. This new security feature might not be added to the core files. You can read more about it from the following URL the-two-factor-plugin-is-currently-on-a.

What does this means for many of you running WordPress? You won’t have to install a Two Factor plugin any more if you had one installed unless you prefer and like the plugin you are using. It also means that it will be extremely challenging for hackers to brute force attack into your website.

Note: You might also be interested in reading the following tutorial Google Authenticator Security WordPress.
