[Cryptography] Security weakness in iCloud keychain

[Kent Borg]

Sounds like they built a very complex system and in that either they 
messed up, or it is confusing enough that the user (you) messed up.

Complex systems are hard to get right. Trusting the passwords for one's 
entire life to such a system seems a bad idea, but that's the current 
trend, everybody's doing it, every expert (that I have seen) is 
recommending it.

This isn't going to end well.

-kb, the Kent who recommends simple solutions, simple enough that the 
user can fully understand it, paper and pencil if necessary.
