Using Touch ID with Amazon App

According to the update in the App Store, the Amazon app now supports login via Touch ID. Has anyone figured out how to use it?

The application keeps you logged in to your account once you log in unless you log out, but if you do anything that would require a password entry like managing your wish list, a Touch ID prompt comes up giving you the option to use your fingerprint instead of typing in your password

Go to settings, scroll down till you find a list of downloaded apps. Locate and tap Amazon app. You will find toggle switch to turn on/off touch id feature. Good Luck.
