I've been googling around on how to store a password, and most of the people say that the only acceptable option is Keychain. I implemented that kind of approach, due to rush. But now I am curious what is that obvious thing to not store passwords in NSUserDefaults and is it ok to store password in CoreData?
So far I understood that NSUserDefaults are stored as a plain text in plist file. But how may one access this file? I've read that it is possible to do with the help of a lightning cable and an itunes, but didn't find how to do that.
Thanks in advance!
Data you store using NSUSerDefault are getting saved in simple plist -in binary format without any encryption. there are many tricks to read these data or modify these data.
Jailbreak users can use iFile to view or modify plist files. Non-Jailbreak users can use other software like iExplore - iFunBox to do this. This software allows users to explore the iOS filesystem without having phone jailbroken
Long story short -- anyone can see or modify data in NSUserDefault. So if you don't want to share your detail publicly, you should never store them in NSUserDefault.
