Which of the following is NOT required to register and log a support request in MOS?

To register and log a support request in My Oracle Support (MOS), a user must provide specific identifiers that link their account to Oracle's support system. One of the key identifiers required is the Customer Support Identifier (CSI), which is a unique number associated with the customer's account. This allows Oracle to properly route and manage support requests.

Additionally, the Tenancy OCID (Oracle Cloud Identifier) is often needed for services in Oracle Cloud Infrastructure, as it identifies the specific tenancy associated with the resources needing support. The resource OCID, which identifies a specific resource within a tenancy, may also be needed if the support request pertains to a particular service or resource.

However, an account password is not required when logging a support request in MOS. Users will already be authenticated when they log in to the system, and the process for raising a support request primarily revolves around the identification of the account through the Customer Support Identifier and related identifiers rather than the password itself. Therefore, the correct answer is that the account password is not a mandatory piece of information for logging a support request in MOS.
