Currently, the Chomp API Client Center does not support changing your account email address directly through the user interface. 

Because your email address is fundamentally tied to your API key and billing history, updating it requires a manual migration by the backend administration team.

If you need to transfer ownership of an account or update your billing email address, please open a support ticket from your current registered email address. Provide the new email address you wish to use, and the Chomp Support team will facilitate the secure transfer.
