<para><command>systemd-logind</command> is a system service that

manages user logins. It is responsible for:</para>

<itemizedlist>
|
|
<listitem><para>Keeping track of users and sessions, their processes and their idle state. This is implemented by
|
|
allocating a systemd slice unit for each user below <filename>user.slice</filename>, and a scope unit below it

|
for each concurrent session of a user. Also, a per-user service manager is started as system service instance of

<filename>user@.service</filename> for each logged in user.</para></listitem>

<listitem><para>Generating and managing session IDs. If auditing is available and an audit session ID is already set for

a session, then this ID is reused as the session ID. Otherwise, an independent session counter is

used.</para></listitem>
