[Prohibit use of key/certificate with
weak encryption]
[Use TPM to store password and key]
When TPM settings are enabled
● Make sure to change the "Administrator" password from the default value, to prevent a third party other
than the administrator from being able to back up the TPM key. If a third party takes the TPM backup key,
you will not be able to restore the TPM key.
● For the purpose of enhanced security, the TPM key can only be backed up once. If the TPM settings are
enabled, make sure to back up the TPM key on to a USB memory device, and store it in a secure place to
prevent loss or theft.
● The security functions provided by TPM do not guarantee complete protection of the data and hardware.
