If you've already gone through setup, but would like to add, update or edit your credentials for an app or service, just click the CAAVO button. Then navigate to Settings>Apps & Credentials>Credentials
You will be asked to use your laptop or mobile device to login and modify your apps and service settings.
If you'd like to add or remove a service, simply select or deselect the service on-screen, then enter the corresponding login and password for that service.
For any other service that you wish to keep the same, simply select "use this account."
When you have completed setup you will be returned to settings.
