1 00:00:02,180 --> 00:00:08,270 It's time to add some users to this application, to add authentication because many apps which you'll 2 00:00:08,270 --> 00:00:15,700 build will have authentication. They need users who can sign up or login or logout to really work 3 00:00:15,710 --> 00:00:21,590 and therefore in this module, we will thoroughly walk through everything that's included with signing 4 00:00:21,590 --> 00:00:23,410 users up, signing them in, 5 00:00:23,570 --> 00:00:29,340 logging them out, giving them access to the backend so that they can send data to protected resources 6 00:00:29,370 --> 00:00:35,650 there and so that only authenticated users can interact with the back-end and so on. We will do all of that 7 00:00:35,650 --> 00:00:40,370 in this module and you will learn how authentication works in native apps like this and how you can 8 00:00:40,370 --> 00:00:42,260 implement it in this React Native app.
