Sometimes when WordPress site is updated ftp details are asked while updating. We can surpass the FTP authentication and directly update WordPress, Plugins and Themes to latest version.
To do so open your wp-config.php file (file is present on the root of wordpress installation).

require_once(ABSPATH . 'wp-settings.php');


After you find the above line in the wp-config.php file place the following line below it.

define('FS_METHOD','direct');


So, your final file should look like below.

require_once(ABSPATH . 'wp-settings.php');
define('FS_METHOD','direct');


After this save you wp-config.php file and upload back to server. Now WordPress, Plugins, Themes can be updated to their latest version without the need to enter FTP details.
