forgot iCloud security key
hi there, I'm unable to access my files/folders that I used to save on the desktop of my MBP. I have 2 devices activated for iCloud- my iPhone + MBP. I would ned help with enabling access on both devices. I have forgotten my iCloud security key and don't know how to authorise my MBP again. thanks
MacBook Pro with Retina display, OS X Yosemite (10.10.2)
