Guided Access is one of the many iOS features being enhanced in iOS 8. Guided Access is used to keep a someone on a single app using a password. For example, if you want your child to read a book and not watch a video you can lock them into the reading app, eliminating the ability to navigate to other apps. With Guided Access enabled, a child or student will need a passcode in order to enter another app. To learn more about Guided Access click here.
One of the enhancement allows users to end a Guided Access session with their finger print using Touch ID. Similar to how third-party developers can implement Touch ID authentication, Guided Access will also take advantage of finger print reading technology. Instead of entering a passcode, users with a Touch ID enabled device will be able to end the session simply by placing their finger on the Touch ID sensor. This feature will simplify the processes of ending Guided Access and potentially eliminate the frustration resulting in forgotten passcodes.
The other enhancement allows students and parents to set a time limit. After the time expires the app will not respond until the correct passcode or finger print is entered. Periodically a small message appears showing how much time is remaining. This feature could be perfect for test taking by ensuring students stop answering questions after the allotted time expires, or for setting a time limit for playing games- when the time limit is reached, the app will not respond.
To enable Guided Access navigate to Settings > General > Accessibility > Guided Access.
