Thanks John, I understand their POV for an iPhone, but iPads tend to be shared devices.....?<br />
<br />
Do you know the answer to my second question?

The iPads I help with here (grandchildren) are single user devices. Yes they might be shared, but login is for one user. Each child has their own iPad. The OS is the same as well. So all the personal devices I am familiar with are one user. <br />
<br />
MAC OS for Computers does have multi-user capability.

Let's say I have an iPad and iPhone (both iOS 10 if it makes a difference). <br />
<br />
I enable TouchID on my iPad and the finger prints stored are that of mine and my wife's.<br />
<br />
1. Many mobile apps now authenticate using Touch ID. Is there any way to restrict/ any plans to, the fingerprint to the app...currently it seems my anyone with their finger print registered can access any app.<br />
<br />
2. If I enable Touch ID on my iPhone, will my wife automatically have access to my apps, or does she need to re-register?

Touch ID and multiple users

iOS is a mobile operating system developed by Apple; it is a derivative of the Mac OS X desktop operating system, with which it shares many (but not all) common frameworks and other components. These include Cocoa Touch, the Mach/Darwin/XNU kernel and code from the Berkeley Software Distribution (BSD). Each iOS application runs in its own secure sandbox to prevent altering other applications, the operating system, or any other data.

iPad is an iOS-based line of tablet computers built around the device's multi-touch screen, including a virtual keyboard. The iPad includes built-in Wi-Fi and cellular connectivity on select models. An iPad can shoot video, take photos, play music, and perform Internet functions such as web-browsing and emailing. Other functions – games, reference, GPS navigation, social networking, etc. – can be enabled by downloading and installing apps.

iPad

The iPhone is a smartphone made by Apple Inc. It and the iPad, along with several other mobile devices from Apple, run on the iOS operating system, which has its own topic, as does the iPad for device-specific questions. Native iOS applications are written in Objective-C or in Swift using the Cocoa Touch frameworks or HTML5 compiled with the help of a package manager such as Adobe PhoneGap; a common IDE is Xcode.
