+#### 🔐 Session Timeout & Auto-Logout (v2.1.0-dev)
+
+**Status**: ✅ Implemented 2025-11-26
+**Purpose**: Auto-logout utenti inattivi dopo 30 minuti per sicurezza
+
+**Componenti Implementati**:
+1. **[SessionTimeoutService.cs](src/InsightLearn.WebAssembly/Services/Auth/SessionTimeoutService.cs)** - Service C# per monitoraggio inattività
+   - Timer inattività con check ogni 30 secondi
+   - Warning countdown 5 minuti prima della scadenza
+   - Eventi: `OnWarningShown`, `OnSessionExpired`, `OnCountdownTick`
+   - Reset automatico su attività utente
+
+2. **[sessionTimeout.js](src/InsightLearn.WebAssembly/wwwroot/js/sessionTimeout.js)** - JavaScript per tracking attività
+   - Event listeners: mousemove, keydown, click, scroll, touchstart
+   - Debounce 5 secondi per performance
+   - Visibility change detection (tab switching)
+   - JSInterop callback `OnUserActivity`
+
+3. **[SessionTimeoutWarning.razor](src/InsightLearn.WebAssembly/Components/SessionTimeoutWarning.razor)** - Componente UI warning
+   - Modal overlay con countdown
+   - Pulsante "Stay Logged In" per estendere sessione
+   - Pulsante "Logout Now" per uscita immediata
+   - Auto-redirect a `/login?expired=true` alla scadenza
+
+**Configurazione** (valori default):
+```csharp
+// In SessionTimeoutService.cs
+public int TimeoutMinutes { get; set; } = 30;    // Timeout totale
+public int WarningMinutes { get; set; } = 5;     // Warning prima della scadenza
+```
+
+**Flusso**:
+1. Utente loggato → Service inizializza tracking
+2. 25 minuti inattività → Warning modal con countdown 5:00
+3. Utente attività → Warning chiuso, timer reset
+4. 30 minuti inattività → Auto-logout, redirect a `/login?expired=true`
+
+**Registrazione** (Program.cs WebAssembly):
+```csharp
+builder.Services.AddScoped<SessionTimeoutService>();
+```
+
+**Integrazione** (MainLayout.razor):
+```razor
+<!-- Session Timeout Warning - Auto logout after inactivity (v2.1.0-dev) -->
+<SessionTimeoutWarning />
+```
