Please follow below instructions to harden your wordpress:
Step 1: Create the Password File
Create a file named .wpadmin and place it in your home directory, where visitors can't access it. (Please note there is a period preceding the wpadmin in that file name.)
(where "username" is the cPanel username for the account.)
Put the username and encrypted password inside the .wpadmin file, using the format username:encryptedpassword
(where "john" is a username of your choice, and the password shown is encrypted.)
Option A: Generate Password File & Uploading Via File Manager

Step 3: wp-config.php set permission to 400
For all the config in wordpress, the permission must be 400.
