Changing id and password for a saved remote computer name

Computer A is saved on my "control computer" as Computer as Computer A.  Recently Computer A crashed and I had to completely reload Teamviewer, which of course now has a different id and password.  I can log in from my control computer by entering the id and password each time.  I would like to replace the id and password stored on my control computer for Computer A, but cannot find a way to do that.
