I’ve set up a droplet for a client, and I’d like him to be directly responsible for billing, while I remain the admin. There doesn’t seem to be any way in the DO control panel of adding extra user who can log in and administer the billing for the account. Am I missing something, or is this indeed not possible? Is the only choice to give him my DO login details so he can add his card to my account?

(Similarly, I can envisage a situation where I might want to allow a colleague access to the emergency console, eg to reboot a non-responsibe server - again, do I need to give them my login?)
