What is keyChain -

Key chain is the place where we can store the values which will be retain even after deleting application. Generally we store username and password in it.

Difference between KeyChain and userDefaults

The values which are store in userDeafults are deleted when we delete the app from our device but the values stored in KeyChain will not.


Apple provides helper classes, for that you can refer to this link
htps://developer.apple.com/library/ios/#samplecode/GenericKeychain/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007797
