Username or Email Text

Hi Elvis,

You can add the following code to your functions.php file to do that:

function login_function() {
    add_filter( 'gettext', 'username_change', 20, 3 );
    function username_change( $translated_text, $text, $domain ) {
        if ($text === 'Username')  {
            $translated_text = 'Thy Username';
        }
        return $translated_text;
    }
}
add_action( 'login_head', 'login_function' );

Hope that works. 🙂
