To allow me to configure your CloudFlare account in a secure way without sharing your login details, login to your CloudFlare account, then from the dashboard (1) Select Manage Account
and then Members
from the Side Panel on the left. (2) Invite a member by entering in my email address and press Invite
. Optionally you can also enable the Member 2FA enforcement
to add additional security.

Additionally it is worth setting up Billing
from the Manage Account
menu on the left to allow the purchase of any new Domain Names.
