Initializing the TPM chip
When you use the TPM function for the first time or you want to
register the user again, you have to initialize the TPM chip.
Initializing the TPM chip erases all authentication •
information saved on the TPM chip. Any decision to
initialize must be taken carefully.
To initialize the TPM chip again while the TPM function is
•
in use, you have to decrypt any existing files and folders
encrypted by the TPM function first. Otherwise, you
will not be able to access the files and folders after re-
initialization.
