I know this dead horse has probably been beaten beyond recognition, but I think the safest option that still preserves some convenience for password management is to stick a keepass database in your cloud storage provider (icloud/dropbox/whatever). Some keepass compatible apps even offer full iOS integration (FaceTime unlock, Password AutoFill), so you don't lose these features you're used to with LastPass.
