How is EFS key protected and unprotected when Windows Hello PIN is used?
EFS private key is normally encrypted by users Windows password, but when PIN (and TPM magic) is used to sign user in using Windows Hello, the user's passphrase is not used at all…so how can Windows access EFS private key since user password is not given?
So, how are user EFS privatekey protected and unprotected as Windows Hello PIN is used?
(I have literally searched everywhere for answers, but got none)
