Yes, you're correct that when a user's session times out and they attempt to execute a settings update request, it will fail due to lack of authorization. In this scenario, you can indeed delete the session cookie on the client side. Here's how you can handle this situation: 1. When the settings update request fails due to an expired session, you'll typically receive a 401 Unauthorized or 403 Forbidden response from the server. 2. Upon receiving this response, you can delete the session cookie on the client side. The exact method to do this depends on your client-side technology, but generally, you'd set the cookie's expiration to a past date. 3. After deleting the cookie, you should redirect the user to the login page to re-authenticate. It's important to note that simply deleting the cookie on the client side doesn't invalidate the session on the server. For proper security, you should also invalidate the session on the server side. Ory provides specific endpoints for handling session management: 1. To check if a session is still valid, you can use the

/sessions/whoami

endpoint as described in the [Ory API Reference](https://www.ory.sh/docs/reference/api). 2. To properly logout and invalidate a session, you can use the

/self-service/logout/browser

endpoint for browser-based flows or the

/sessions

endpoint for API-based flows, as detailed in the [Ory API Reference](https://www.ory.sh/docs/reference/api). 3. For settings flows specifically, Ory has a built-in mechanism to handle expired sessions. As mentioned in the [Ory Kratos User Settings & Profile Management Documentation](https://www.ory.sh/docs/kratos/self-service/flows/user-settings): "If the Ory Session is older than the specified amount, the user is prompted to re-authenticate similar to the GitHub sudo mode." This means that for browser-based flows, Ory will automatically redirect the user to re-authenticate if the session has expired during a settings update attempt. For API-based flows, you'll receive a 403 Forbidden status, at which point you should initiate a new login flow as described in the [API-based Login Flow documentation](https://www.ory.sh/docs/kratos/self-service/flows/user-login). Remember, it's crucial to handle session expiration securely on both client and server sides to maintain proper security in your application.
