Managing use of management controller secrets based on firmware ownership history

A management controller of a computer platform, determines whether an ownership history of management firmware for the management controller represents multiple owners. The management controller includes a set of one-time programmable elements that represent a first secret. The management controller manages use of the first secret based on the ownership history. The management includes, responsive to determining, by the management controller, that the ownership history represents multiple owners, generating, by the management controller, a second secret to replace the first secret. The management further includes, responsive to determining, by the management controller, that the ownership history represents multiple owners, storing, by the management controller, the second secret in a non-volatile memory and generating, by the management controller, cryptographic keys based on the second secret.
