## Description

`systemd-logind` is a system service that manages user logins. It is responsible for:

- Keeping track of users and sessions, their processes and their idle state

- Creating control groups for user processes

- Providing PolicyKit-based access for users to operations such as system shutdown or sleep

- Implementing a shutdown/sleep inhibition logic for applications

- Handling of power/sleep hardware keys

- Multi-seat management

- Session switch management

- Device access management for users

- Automatic spawning of text logins (gettys) on virtual console activation and user runtime directory management

User sessions are registered in logind via the pam_systemd(8) PAM module.

See logind.conf(5) for information about the configuration of this service.

See Multi-Seat on Linux for an introduction into basic concepts of logind such as users, sessions and seats.

See the logind D-Bus API Documentation for information about the APIs `systemd-logind` provides.
