This feature adds a comprehensive session tracking system to the Security tab, displaying the last 10 active sessions for each user with details including browser, location, IP address, sign-in method, and activity timestamps. Users can review their login history to identify suspicious activity and take immediate action through a "This wasn't me" button that triggers a security workflow to sign out all sessions and prompt password changes. The system will track sessions through secure device fingerprinting and cookies, giving users visibility and control over where their account is being accessed while helping prevent unauthorized access.
