OpenPAM is a BSD-licensed implementation of the PAM (Pluggable Authentication Modules) framework. FreeBSD, NetBSD, DragonFly BSD, and macOS adopt it as their default PAM library, and it is a separate codebase from Linux-PAM, which Linux distributions mostly use. The PAM API itself, which combines authentication modules through configuration files, is nearly the same in both implementations, but they differ in configuration file locations and supported modules.
