Course description
Access control is one of the most basic security mechanisms you can implement on a device or in the app itself. Good access control reduces the initial risk of attack or accident. In this course, you will learn about authentication and authorization. You will utilize Android’s strongest authentication mechanisms, including two-factor, biometric and one-time password logins. You will also learn about the different authorization types and implement the most common of these in your app. You will then learn to manage risks associated with IDOR and uncontrolled sessions.
