**Automatic Rotation**: Keys regenerated on each application load - **Secure Cleanup**: Complete token removal on logout ### Device Trust - **Hardware Fingerprinting**: Based on browser, platform, screen, timezone - **Trust Duration**: Configurable trust periods (7, 30, 90, 365 days) - **Trust Tokens**: Separate tokens for device trust validation - **Remote Revocation**: Server-side device trust management ### Session Management - **Configurable Timeouts**: Adjustable session timeout periods - **Activity Monitoring**: Tracks user activity for session extension - **Concurrent Sessions**: Multiple session tracking and management - **Graceful Logout**: Clean session termination with server notification ### WebAuthn Security - **Hardware Security**: Leverages hardware security modules - **Biometric Verification**: Touch ID, Face ID, Windows Hello support - **Security Key Support**: USB, NFC, Bluetooth FIDO2 keys - **Attestation Validation**: Hardware authenticity verification ## 📱 Component Usage Examples ### Basic Authentication Flow ```rust use leptos::*; use control_center_ui::auth::provide_auth_context; use control_center_ui::components::auth::*; #[component] fn App() -> impl IntoView { provide_meta_context(); // Initialize auth context with API base URL provide_auth_context("http://localhost:8080".to_string()).unwrap(); view! { } } ``` ### Login Page Implementation ```rust #[component] fn LoginPage() -> impl IntoView { view! {
