To disable password caching, follow these steps

Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
On the Edit menu, click New, and then click DWORD Value.
Type DisablePasswordCaching to name the new registry entry, and then press ENTER.
Right-click DisablePasswordCaching, and then click Modify.
Make sure that the Hexadecimal option button is selected, type 1 in the Value data box, and then click OK.
Quit Registry Editor.
You can also disable password caching by using the Microsoft Internet Explorer Administration Kit (IEAK) to create an executable file, and then attaching it as an add-in component. When you use this method, Setup adds the DisablePasswordCaching entry to the registry during the installation process.
Note In some cases, you can create a custom .adm file to modify this registry key, and then import it into the IEAK Wizard.
To re-enable password caching, you can either delete the DisablePasswordCaching entry, or change its value to 0.
