Could you please clarify if you mean the passwords that were saved for your remote Host connections in your address book or if you mean passwords that are stored on your remote Host machine (e.g. inside of your browser)?
Unfortunately, it’s not possible to display the passwords saved in the connection property window due to security reasons. In case if the access password for a remote Host was forgotten, then you should reset its password following this guide. Alternatively, you can also fully reset Host settings by deleting the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Usoris\Remote Utilities Host. Please note that deleting this key resets all of the Host settings to default values.
Do you mean restarting Host after changing the password? Please note that you don’t need to stop the Host service in order to change the password. Simply use the Remote Settings and change the password following this guide. When you press OK the changes are applied automatically and Host is restarted automatically as well, so there’s no need to stop Host manually. Just give it a couple of minutes to restart automatically and you should be able to connect using your new password.
