      On a Linux server, if the password protection directory for "/" does not exist, open the .htaccess file via Plesk File Manager and remove the following lines:

      AuthType Basic
      AuthName "Secure Content"
      AuthUserFile /var/www/vhosts/example.com/httpdocs/.htpasswd
      require valid-user

 

Solution II: Add a user in Plesk and allow him to access the website with the password

 

Add a user in Plesk and allow him to access the website with a password using the steps from this KB article.
