We are working based on a project requirement to use Bitlocker Auto-Unlock feature in a FIPS-GPO-enabled environment. Unlocking the bitlocked devices with passwords, in a FIPS-enabled environment will make them write-protected. Using a recovery key or a recovery password does not opt for our requirement.

But we can make use of this Auto-unlock feature to overcome the present situation.
So, before enabling the auto-unlock, want to know the details regarding the following queries.

1) How do windows securely manages this auto-unlock feature and how does it work internally?
2) Also, What are the security assurances of using auto-unlock feature for portable devices?

Any help would be appreciated.
