I need to safely manage passwords stored in memory on Xamarin.IOS.

What is the best way to leverage C# to securely erase the sensitive data?

This Sec.SE link references the details on why we need to pay special attention to this risk

Use keychain for secure data. Perhaps this example is illustrative: https://developer.xamarin.com/samples/monotouch/Keychain/. For broader discussion of security in apps, see WWDC 2015 video [Security and Your Apps](https://developer.apple.com/videos/play/wwdc2015/706/). – Rob May 18 '16 at 17:36
You could also use SecureString, see http://stackoverflow.com/questions/141203/when-would-i-need-a-securestring-in-net – Crackerjack May 18 '16 at 17:37
