it doesn't work within apps!! So I register on an EasyJet site, my Safari browser suggests a super strong password. Perfect. I then launch my EasyJet app, it tells me to log back in as my password has changed, and then I have to open Keychain on my Mac again, find the EasyJet entry, right click it, open info, type in my secure OS X Password, click the Show Password button, then spend 10 minutes manually typing in this ridiculously long and secure password into my EasyJet app - all while on the move!! This is the same for all my other airline apps, for Facebook, for Twitter, for LinkedIn and so on... Very disappointing - they clearly didn't think about this use case when developing and testing it... Nice idea Apple, but unless you're going to extend Keychain into iOS apps, then it's almost unworkable / too unwieldily.
