# Configuring PAM Authentication

You can configure PAM by creating a configuration file or configuration entry for the PAM service.

Note: It is critical that you work with your system administrator to configure the PAM service settings. Each system might configure PAM slightly differently. The system administrator has to review the PAM requirements for your system before making any PAM changes.

The following PAM module types are used.

PAM Module Type | Description
--- | ---
`auth` | Used to authenticate the user id and password credentials.
`account` | Used to validate that the authenticated user is able to access the system.
