Does the Keychain in iOS actually work?

Keychain is a software which is used in Apple iOS devices as secure storage for sensitive and confidential data such as login password, keys, tokens, WiFi password etc. Default security settings of iOS are not sufficient for protection of such sensitive data. As there are many versions of iOS available, some of them can be affected by hackers attack. This security threat gives rise for the need of a robust external manual protection like the Keychain.

Each iOS application has its own separate group of keychain softwares. From the iOS 3.0 it is possible to share your keychain software’s across the various applications. In the programming of iOS there are some of the wrappers classes which always work with keychain software. These wrapper classes are used, to store your sensitive information.
