If you have already enabled FileVault disk encryption with an iCloud account as the recovery option, you will need to decrypt and re-encrypt your Mac's disk(s) to use a FileVault Recovery Key. UCSF does not want or need your iCloud password - a Recovery Key is a code specific for encryption on your Mac and does not allow access to your iCloud account.

In some cases, you may not have a FileVault Recovery Key because macOS will allow you to use your iCloud login to unlock your Mac, but this does not satisfy the Proof of Encryption requirements as part of UCSF and UC policy. If a Mac cannot use UCSF's Jamf Pro, the Proof of Encryption form can be used to provide evidence of encryption and also escrow an FileVault Recovery Key with UCSF. If you cannot use Jamf Pro, use the Proof of Encryption form and a FileVault Recovery Key
