Overview

This module ensures that when a user tries to log in from another device or browser while already logged into the system, a warning message is shown: “User is already logged into the system from another device.” The user must manually log out from the previous session before being allowed to log in again. This prevents multiple active sessions for the same user, ensuring a secure single-login environment. It enhances session control and improves the overall security of the system by allowing only one active session per user at a time.
