FDKeychain is a static and open source iOS class that has three simple methods: save, load, delete.
FDKeychain allows developers to take any object that conforms to the NSCoding protocol and easily save it to the keychain. The saved key can then be used to load or delete the object from the keychain.
The iOS keychain is a simple yet powerful not application specific password management system.
Detailed instructions on how to install and use FDKeychain within your own iOS apps are available HERE.
