The Steps to initially activate the Oracle Cloud after purchasing are describes below:

https://docs.oracle.com/en/cloud/get-started/subscriptions-cloud/csgsg/activate-your-order-your-welcome-email.html

With the activation the customer chooses the Account Name (or actually Tenant Name) of their Service, that will be displayed in all subsequent URLs and in the background the Oracle Cloud is physically provided within the chosen Data Center region e.g. EMEA and the Cloud Console will be made available (via DNS configuration in the Oracle Cloud) with the specified Account Name and services like IDCS (Identity Domain Service) are started to maintain the User(s). The Person who conducts this initial activation is also the Cloud Service Administrator and from now on the only person to be able to add further Users as Cloud Service Administrators.

After completion of the steps from the activation link, the user receives another e-mail to his e-mail address with a provisioned user (from IDCS) and a new temporary password to change on the next login.
