No cases in this browser
Cases are saved to the browser you created them in — there is no account and no password. If you analysed a notice on another device, or cleared your browsing data since, this list will be empty even though nothing went wrong.
There is no account behind this list. The way back to your cases is stored in this browser, so clearing your browsing data, using private browsing, or switching device will lose it. What you wrote in your own words was never saved at all.
