Translations:PAM/4/en

Authentication management (part of access management) on a Linux server can be handled by PAM (Pluggable Authentication Modules). With PAM, services do not need to provide authentication services themselves. Instead, they rely on the PAM modules available on the system. Each service can use a different PAM configuration if it wants, although most of the time authentication is handled similarly across services. By calling PAM modules, services can support two-factor authentication out-of-the-box, immediately use centralized authentication repositories and more.
