I have been working on this for a while, and I am trying to use .htaccess and .htpasswd. Here is what I have done:

Performed with Apache using Raspberry Pi 3B+ with DietPi installed.

• I created a new .htpasswd file and proceeded to enter password that I wanted.

• Next, I redirected to /etc/apache2/sites-enabled/ where I edited 000-default.conf and changed the line of code:

  <VirtualHost *80>
  ServerName www.example.com
      ServerAdmin webmaster@localhost
      DocumentRoot /var/www/
  
      ErrorLog ${APACHE_LOG_DIR}/error.log
      CustomLog ${APACHE_LOG_DIR}/access.log combined
  
      <Directory "/var/www/etc/"
          AuthType Basic
          AuthName "Restricted Content"
          AuthUserFile /etc/apache2/.htpasswd
          Require valid-user
      </Directory>
      RewriteEngine on
      RewriteCond %{SERVER_NAME} =example.com
      RewriteRule ^https://%{SERVER_NAME%{REQUEST_URI} [END,Ne,R=permanent]
  </VirtualHost>
  

Everything here is the same, except replace "example" with my domain.

This did not affect my site, so I redirected to /etc/apache2/ where I edited apache2.conf and added the line of code:

<Directory /var/www/etc/>
    DirectoryIndex index.php index.html
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all denied
</Directory>

Once again, everything here is the same. etc is the file that I want to password-protect. This made the page that I wanted to protect completely inaccessible, and when I changed AllowOverride and Require all it just made the page completely open. How can I make it so that a password is prompted when you try to access the directory?
