Filevault Recovery Key vs. iCloud Recovery Key
I have two step verification set up for my iCloud account meaning I already have been provided a recovery key in case I cannot login otherwise. I have recently turned on FileVault and selected the option to have my iCloud account decrypt the disk, not through a recovery key. However, now the FileVault setting in System Preferences says that "A recovery key has been set." Is this recovery key the same as that made initially when I set up two-step verification through iCloud or is it some other recovery key, which I never received.
