How can HTTP authentication be used effectively to secure phpMyAdmin access?

To secure phpMyAdmin access using HTTP authentication, you can create a .htpasswd file with username and password credentials, and then configure the .htaccess file to require authentication before accessing phpMyAdmin.

// .htpasswd file
// username:password
// Generate password using htpasswd tool or online generator
// Place this file outside the web root directory for security

// .htaccess file
AuthType Basic
AuthName "Restricted Area"
AuthUserFile /path/to/.htpasswd
Require valid-user
