 If you reload your app, you will see two plain `TextInput` boxes which can accept input. As these are updated, the `onChangeText` prop is triggered
 which then updates state for that specific value. The inputs then individually update whenever their `value` from state changes:

 [`ActivityIndicator`](https://facebook.github.io/react-native/docs/activityindicator.html). You'll also want to handle any errors back from
 Firebase to show to your user!

+The logic for registering or submitting a forgot password request is exactly the same as our sign in logic. Simply follow the same pattern
+as we've done above using `TextInput` components and state. Once you've got the desired information, call Firebase with the methods you need, such as
+[`createUserAndRetrieveDataWithEmailAndPassword`](https://rnfirebase.io/docs/v3.2.x/auth/reference/auth#createUserAndRetrieveDataWithEmailAndPassword)
+or [`sendPasswordResetEmail`](https://rnfirebase.io/docs/v3.2.x/auth/reference/auth#sendPasswordResetEmail)!

+Remember to allow the user to navigate between these screens using the `navigate` method provided by `react-navigation`.

+screens which is another common navigation pattern.
