htpasswd: User Authentication for Apache Web Servers

htpasswd is a command line tool used for managing user authentication in Apache web servers. It allows you to create and manage user accounts and passwords for accessing protected areas of a website. The htpasswd file is typically stored in a secure location on the server and contains encrypted passwords for each user. When a user attempts to access a protected area of the website, Apache checks the htpasswd file to verify the user's credentials before granting access.
