Getting cryptography right on Android is challenging. There are code examples without much explanation about what is really going on.
In this talk you will learn the details you need to implement a subset of Android security: user authorization.
We will discuss how to implement robust user authorization using the new Fingerprint API and the Android Keystore,
and we will explore how to correctly use the Keystore to keep your application secrets secure.
