When the computer starts, it can use only the TPM for authentication, or it can also require insertion of a USB flash drive containing a startup key, the entry of a 6-digit to 20-digit personal identification number (PIN), or both.</p>

>In TPM 2.0 if minimum PIN length is set below 6 digits, Windows will attempt to update the TPM lockout period to be greater than the default when a PIN is changed. If successful, Windows will only reset the TPM lockout period back to default if the TPM is reset. This does not apply to TPM 1.2.
