Sessions store user data across requests, configured via config/session.php with drivers like file, database, cookie, or Redis. Data is accessed with session('key') or $request->session()->get('key'), and flash data persists only for the next request (useful for one-time success messages). CSRF tokens, generated per session, protect state-changing forms.
