Apple Store app updated to support Touch ID and two-step verification
The update also adds two-step verification to the app. This will be used only when placing an order. With this security feature, you type in your Apple ID and password and are sent a verification code to one of your iOS devices. Enter the code and your identity is verified.
The updated version 3.3 of the Apple Store app is now available from the Apple App Store where it is a free download. Besides the two-step verification and support for Touch ID, the Apple Store app is now available for use in a few new countries such as Turkey, Brazil, Mexico, Singapore, New Zealand, Taiwan, Malaysia, Philippines, United Arab Emirates, Belgium, Denmark, Finland, Austria, Ireland, Luxembourg, Norway, Czech Republic, Hungary, Poland and Portugal.
