The 'Remember Password' feature, when checked, triggers a mechanism on the server which sends back your authentication data to your browser and requests that it be stored temporarily. The data, or 'cookie' as it is commonly referred to, is then resent by your browser to the server upon each subsequent request you make. This form of data exchange is not uncommon and is preferred in lieu of passing your authentication information embedded in hidden form elements or in plain sight as an argument in URLs.
