tpm_setclearable(8) FreeBSD System Manager's Manual tpm_setclearable(8)

TPM Management - tpm_setclearable

tpm_setclearable - disable TPM clear operations

tpm_setclearable [OPTION]

tpm_setclearable reports the status of the TPM's flags regarding how the TPM can be cleared. This is the default behavior and also accessible via the --status option. Requesting a report of this status prompts for the owner password. The --owner option requests that the TPM disable clear operations (via the TPM_DisableOwnerClear API) disabling the owner from clearing out the ownership information. This operation prompts for the owner password. This operation is in effect until the current owner is cleared. The --force option (via the TPM_DisableForceClear API) disables using Phyiscal Presence to authorize a clear operation. This operation does not require authorization and will skip the owner password prompt. This operation is only in effect until a reboot.
