NSUserDefaults is just a handy way designed for customize app's preferences. In normal situation, an app will stay in it's own sandbox and therefore other apps won't be able to access it.

However it is not the best choice to do so. It's not good practice. What you really need is keychain and see here for apple's sample code for it, it's much safer in terms of security.

As others have suggested, you can use NSUserDefaults.

If you are storing the password, then I would suggest you also add a level of security to this. You could use Secure NSUserDefaults (I've not used this personally, but seen a few people reporting it being useful). You can find that here

Or you can use the KeyChain API

You can save this in the NSUserDefaults like this :

NSUserDefaults *userDefaults = [NSUserDefaults standardDefaults];
[userDefaults setBool@"YES" forlkey@"userDidLogin"];

And you test like this :

NSUserDefaults *userDefaults = [NSUserDefaults standardDefaults];

if([userDefaults boolForKey:@"userDidLogin"])
{
.... // Go to the list View
}

This is just an indication, if you would like to put it to work , you should show your code how you implement the implémentation of login interface

If you do not care about encryption, you could save these very simply with 

[[NSUserDefaults standardUserDefaults] setValue:@"username" forKey:@"username"]; 
[[NSUserDefaults standardUserDefaults] setValue:@"secret" forKey:@"password"];

and check those during program startup with

if (![[NSUserDefaults standardUserDefaults] valueForKey:@"username"]) {
   // show the login screen
}
