I cannot edit an Account password

I have changed the password to my Gmail account using the Gmail web page.

Now I cannot see how to edit the password from eM Client.

If I go to Menu | Tools | Accounts I do not see a field for Password in any of the tabs.

I also note that since I changed the password and eM Client can, presumably, not log in to my gmail account. that eM Client no longer displays the Account in the side bar.

How do I edit the password?
