Filevault 2 enabled with recovery key linked to Apple ID, can I get the key? I enabled FileVault on my Yosemite Mac, and selected the "Allow apple ID to reset password" option.

I paid attention to all the dialogs and though they said to write down my recovery key, it was never shown to me.

Did something go wrong? When I did this years ago with FileVault 1 I was shown the key.

I tested using the Apple ID "change password" function and it seemed to work OK but I'd like to have a copy of the key written down as an extra safety measure.
Since you can still decrypt the drive. I suggest you disable filevault now then enable it again, to get a new code. This time don't save the code to the apple cloud but copy it and email it to yourself.
