Pluggable Authentication Modules (PAM) provides a system of libraries that handle the authentication tasks of applications (services) on a Linux system. These libraries are loaded dynamically and can be configured in the/etc/pam.ddirectory or in/etc/pam.conf. The PAM modules are divided into four types:

auth (authentication):This module type is responsible for authenticating the user, setting up user credentials, and initiating a session.

account:This module type manages account policies such as password expiration, access restrictions, and checking user permissions.

password:This module type handles the updating of authentication tokens, such as passwords.

session:This module type manages tasks that need to be performed at the beginning and end of a session, like mounting directories or logging.
