In computing, a login session is the period of activity between a user logging in and logging out of a (multi-user) system.

On Windows NT-based systems, login sessions are maintained by the kernel and control of them is within the purview of the Local Security Authority Subsystem Service (LSA). codice_1 responds to the secure attention key, it requests the LSA to create login sessions on login, and terminates all of the processes belonging to a login session on logout.
