secure wp-config and then edit

I have secured my wp-config file by adding this code to my .htaccess file:

# protect wpconfig.php
<files wp-config.php>
order allow,deny
deny from all
</files>

Now I like to know this: is it still possible for me to edit the wp-config file and add code to it? For example: can I edit the wp-config file in my webshosts DirectAdmin control panel?

Or is it not possible to edit the wp-config file with this code in .htaccess? And do I have to delete the code in .htaccess first, before making any new changes in wp-config?

Thank you for your help ??
