Security Device
This option becomes available if Embedded Device is set to Available.
Embedded Security Device (Hidden or Available) turns the Trusted Platform Mechanism (TPM) on
and off. Device Hidden is the default. If this option is made available, the following options
become available:
●
Power-On Authentication Support—Enables and disables an authentication feature that
requires you to enter a TPM user key password to start the computer. This feature uses the
TPM to generate and store the authentication password.
●
Reset Authentication Credential—Resets the authentication functionality and clears
authentication credentials.
To enable the Embedded Security Device and to access any security features associated with the
device, you must enter a setup password.
