Login Error Messages: How To Hide Them For Improved Security

Steven 3 responses WordPress

WordPress being the most-used Content Management System worldwide, a lot of people are searching for holes in its security. Luckily, the WordPress development team is making an amazing job at keeping all of our blogs safe, as long as we keep downloading and installing upgrades.

Whenever someone (you or anyone else) tries to log into your WordPress blog but fails, WordPress displays an error message to let you know what just happened. While it may be useful for you, it may also give some information to potential blog hackers who are trying to break into your blog.

To improve your WordPress blog, an interesting step you can take is disabling these messages. To do so, simply paste the following code in the functions.php of your WordPress blog:

add_filter('login_errors',create_function('$a', "return null;"));

    Hi Steven,

    This is a nice little snippet. Do you know if it still shows the red box that surrounds the error, except with nothing inside it, or does it just bring up a fresh copy of the login page, looking no different than if you had not tried to log in at all?

    1. Yep, I know.

    Yes, thats a helpful info. But my theme doesn’t have functions.php file. Instead it has theme-functions.php file.
