You can’t do this in the central settings app. It is not possible to run your own code there, you can just tell it what sorts of data can be input.

Apple, of course, are not bound by this restriction so they can do what they like in the settings app.

If you want login controls and authentication then this would have to be done within your app – which makes sense from the users point of view anyway, they don’t want to have to switch to settings to start using your app.
