Modifying default WordPress admin login URL create security by obscurity.
Step 1: Locate wp-login.php file in Plesk Dashboard and copy its contents. Go to Files > httpdocs > wp-login.php.
Click and copy all the contents.
Step 2: Create a file with same name that you would like to add to the end of your login URL. For example,
in order to access admin login via URL domain.com/viewhere, you can create viewhere.php and
paste the wp-login.php code into the file.
Step 3: Open the newly created login file and replace all references to wp-login.php with the new .php file's name
Step 4: Backup the unaltered wp-login.php. Upon file downloaded, tick the wp-login.php box and click
'Remove' on top of the page to remove in server.
Step 5: Access the new login page via the URL you have chosen.
