Login manager
open-in-new
<p>A login manager is a <a href="/facts/Login/xNRgTVnV">login</a> system for <a href="/facts/Unix/0pNL2seI">Unix</a> and <a href="/facts/Unix-like/YAKrAxzd">Unix-like</a> <a href="/facts/Operating_system/8XTuvMh2">operating systems</a>. It comprises a login <a href="/facts/Daemon_(computing)/bzuEVGGX">daemon</a>, a login <a href="/facts/User_interface/e9sPEWVD">user interface</a>, and a system for tracking <a href="/facts/Login_session/plmwnSNU">login sessions</a>. When a <a href="/facts/User_(computing)/zQRzG0KG">user</a> tries to log in, the login manager passes the user's credentials to an <a href="/facts/Authentication/64y4S69b">authentication</a> system. </p><p>Since an <a href="/facts/X_display_manager_(program_type)/BpMtjNMQ">X display manager</a> is a <a href="/facts/Graphical_user_interface/wBlQFWDP">graphical user interface</a> for login, some people use the terms <i>display manager</i> and <i>login manager</i> synonymously. </p><p><a href="/facts/Systemd/zls5HoVh">systemd</a>, an <a href="/facts/Init/0NuCuc1g">init</a> daemon for <a href="/facts/Linux/9FvCKSTq">Linux</a>, has an integrated login manager; its login daemon is called logind. systemd's login manager is a replacement for the no longer maintained ConsoleKit. </p>
