I have several domains on our Cloudflare account which we manage for clients. Is it possible to grant a specific client access to just their domain and not to others?
I can see the ability to add additional administrators of all accounts but not to restrict that to just the one domain.
My preference was for us to handle our clients billing & technical communications as well so that we can make sure nothing lapses having experienced clients not realising the importance of things like domain renewals.
Make a unique account for each customer, and then if desired, grant permission to your main account(s). Use email addresses in a dedicated sub domain so there are no conflicts and the naming scheme is consistent:
