Update Unique Keys


In an effort to help make WordPress installations more secure, this plugin will use the WordPress hosted Unique Key generator to update the wp-config.php file with the following keys/salts:


If the wp-config.php file is not writable, then the plugin will show the key / salt values on the plugin options page so the admin can then manually update the wp-config.php file.


  • Output when wp-config.php is not writeable.
  • Output when successful.


Note: As is the case when installing any new plugin, it’s always a good idea to backup your blog data before installing.

  1. After downloading the Update Unique Keys plugin, unpack and upload the file to the wp-content/plugins folder on your blog. Make sure to leave the directory structure of the archive intact so that all of the Update Unique Keys files are located in ‘wp-content/plugins/updateuniquekeys/’
  2. You will need to activate the Update Unique Keys plugin in order to update your wp-config.php file. Go to the Plugins tab and find Update Unique Keys in the list and click Activate.
  3. After activating proceed to the plugin settings page (under Settings > Update Unique Keys) to update your keys and wp-config.php file.
  4. You will be automatically logged out, due to the keys changing, simply re-login with the same username and password.
