Whilst struggling with database credentials on the edit page for an origin I tried 3 different credentials, deleting the previous ones before adding a new one. Finally I tried to go back and add in a credential I had already used and it said it already existed in /auth/credentials/. I will have to edit the credentials there individually in order to delete them because there is no way to add one back into the list of credentials in the origin. I think they must either be deleted when I removed them from the origin or you must be allowed to add existing credentials.
