This management system runs under a user's password. Should you let this software manage your Disk Utility encrypted folder passwords and the like (e.g. GnuPG!)? My thoughts are, "No." Why should there be a software on my operating system that deals with my security? The way I do things is keep a spreadsheet in an encrypted file with all my passwords and never tick 'yes' to 'Remember this password?" prompts. Why should OS X compromise me in this way? What is the perspective of a true information security practitioner who knows better than Macintosh?
