Is it possible to extract keys from iOS Keychen, if user has set no passcode?
===

If i have a password which is saved in the ios keychain, is it possible to "extract" that key from keychain if the user hasn't set a passcode?
As far as i know the passwords from keychain will be decrypted on unlocking the device. Without a passcode everyone could unlock an iDevice and extract passwords from keychain, isn't it?

My problem ist, i don't know if it is enough to save passwords from my app in ios keychain.
