I needed to add a simple message to the WordPress login screen today. I wanted to add it just below the WordPress logo.

Here is the final result of my efforts

While digging around in wp-login.php, I noticed that there is a filter for “message”. So, I simply added an “add_filter” function to functions.php as follows:

add_filter ( 'login_message', 'add_login_message' );
function add_login_message () {
	echo '<div>MY MESSAGE HERE</div>';
}

That’s it! Based on the above, it seems like it would be pretty easy to create a plugin that does this. Heck, I wouldn’t doubt if that plugin already exists.
