Progressive Web Apps (PWAs) rely on service workers, which are scripts that run in the background, to handle user session management and timeouts effectively. Here are the key ways in which PWAs manage user sessions:
- Token-based authentication: PWAs often use token-based authentication mechanisms to manage user sessions securely. Tokens are generated upon user login and are stored locally on the device to authenticate subsequent requests.
- Offline data storage: PWAs can cache data locally using service workers, allowing users to access content even when offline. This cached data includes user session information, ensuring that users remain authenticated even without an internet connection.
- Monitoring user activity: JavaScript code in PWAs can monitor user interactions and track session duration. If a user remains inactive for a specified period, the PWA can trigger a timeout and log the user out automatically to enhance security.
