However, when enrolling for a certificate on Windows, there is no way to indicate that the key associated to the certificate is migratable or not. A safe guess would be that the choice is made by Windows. SpletFor non-migratable keys, the migration secret is tpmproof, a value internal to the TPM and never exposed. Also, the source TPM-owner must approve the destination, however, for any migratable key, the owner can choose any destination. Thus, if the TPM owner is not trusted, the key can end up in any TPM, or even outside a TPM if the
