Introduction
In this tutorial we learn how to install authselect on CentOS 8.
What is authselect
Authselect is designed to be a replacement for authconfig but it takes a different approach to configure the system. Instead of letting the administrator build the PAM stack with a tool (which may potentially end up with a broken configuration), it would ship several tested stacks (profiles) that solve a use-case and are well tested and supported. At the same time, some obsolete features of authconfig are not supported by authselect.
We can use yum or dnf to install authselect on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install authselect.
