In that lesson, we built Fun Food Friendsan application for planning your next potluck. It looked like this:. When signed out, it will look like this:. When users are not signed in, they will be unable to see what people are bringing to the potluck, nor will they be able to add their own items. Your name will be automatically added to the Add Item section, and your Google photo will appear in the bottom right-hand corner of the screen.

You will also only be able to remove items you added to the potluck. Then click on the Authentication tab. You should see something that looks like this:. Firebase can handle authentication by asking the user for an email and password, or it can take advantage of third-party providers such as Google and Twitter in order to take care of authentication and authentication flow for you.

Remember when you first logged in to Firebase, it used your Google credentials to authenticate you? Firebase allows you to add that feature to apps that you build. Everything will be managed through a popup. Hover over Google, select the pencil on the right hand side of the screen, and click E nable in the box that appears.

Finally, hit Save. Now, click Database on the left hand side of the screen, and head to the rules panel. It should look something like this right now:. In the first iteration of our fun food friends app, anyone could read and write to our database. Change your rules so that it looks like this, and hit Publish :. These rules tell Firebase to only allow users who are authenticated to read and write from the database. Here we set the default value of user to be null because on initial load, the client has not yet authenticated with Firebase and so, on initial load, our application should act as if they are not logged in.

If the value of user is truthy, then it means that the user is currently logged in and should see the logout button. If the value of user is null, it means that the user is currently logged out and should see the log in button. The onClick of each of these buttons will point to two functions that we will create on the component itself in just a second: login and logout.

The login method, which will handle our authentication wth Firebase, will look like this:. Here we call the signInWithPopup method from the auth module, and pass in our provider remember this refers to the Google Auth Provider. This callback will be provided with a result object that contains, among other things, a property called.

We then store this inside of the state using setState. The logout method is incredibly straightforward. After the login method inside your component, add the following method:. With this. As of right now, every time you refresh the page, your application forgets that you were already logged in, which is a bit of a bummer.

But Firebase has an event listener, onAuthStateChangethat can actually check every single time the app loads to see if the user was already signed in last time they visited your app. If they were, you can automatically sign them back in.

When the user signs in, this checks the Firebase database to see if they were already previously authenticated. If they were, we set their user details back into the state. That way, only signed in users see the potluck list and have the ability to add new items.Check out the repo to get the code. Firebase Phone Number authentication offers a form of passwordless authentication, wherein users are authenticated on their access to another secure platform, instead of authenticated based on their possession of a password.

The secure platform in the case of Firebase phone number authentication is the user's cell phone. Authentication requires the users to have both the correct cell phone number and physical access to that phone.

However, authentication using only a phone number can also be less secure than the other available methods because possession of a phone number can be easily transferred between users. If you don't already have a Firebase account, sign up for one. In your fresh project directory, create an index. Now, go back to the overview screen for your project and click on it.

Then click Add Firebase to your Web app. A popup will show like so:. We are fleshing out our app little by little. The firebaseui-container div will contain our login button. The app. This leads us to the next stage. The getUiConfig function is responsible for configuring the kind of authentication provider we want.

The Phone Number and Twitter login options were specified here.


The first property in the getUiConfig is the callbacks. It takes in the currentUsercredential and redirectUrl arguments, then calls the handleSignedInUser function.

The function displays the user's details on the screen. The handleSignedOutUser function does the same thing when the user signs out.

The function below simply listens to authentication state changes and displays the right UI based on those changes. The initApp function simply adds event listeners to the sign-out and delete-account buttons. When any of these buttons are clicked, they execute their respective handler functions. Note: The twitter button login does not work.

It is just there to beautify the UI and give the user a feel that there is an alternative login option. In production, there should always be alternative login options. Click on the Sign in with phone button.

The easiest way to add phone number sign-in to your app is to use FirebaseUIwhich includes a drop-in sign-in widget that implements sign-in flows for phone number sign-in, as well as password-based and federated sign-in.

This document describes how to implement a phone number sign-in flow using the Firebase SDK. Authentication using only a phone number, while convenient, is less secure than the other available methods, because possession of a phone number can be easily transferred between users. Also, on devices with multiple user profiles, any user that can receive SMS messages can sign in to an account using the device's phone number.

If you use phone number based sign-in in your app, you should offer it alongside more secure sign-in methods, and inform users of the security tradeoffs of using phone number sign-in. Firebase's phone number sign-in request quota is high enough that most apps won't be affected. However, if you need to sign in a very high volume of users with phone authentication, you might need to upgrade your pricing plan.

See the pricing page. The aforementioned localization will also apply to the SMS message sent to the user, containing the verification code. For example:. To initiate phone number sign-in, present the user an interface that prompts them to provide their phone number, and then call signInWithPhoneNumber to request that Firebase send an authentication code to the user's phone by SMS:. Legal requirements vary, but as a best practice and to set expectations for your users, you should inform them that if they use phone sign-in, they might receive an SMS message for verification and standard rates apply.

Then, sign in the user by passing the code to the confirm method of the ConfirmationResult object that was passed to signInWithPhoneNumber 's fulfillment handler that is, its then block. If the call to confirm succeeded, the user is successfully signed in.

If you need to get an AuthCredential object for the user's account, pass the verification code from the confirmation result and the verification code to PhoneAuthProvider. You can whitelist phone numbers for development via the Firebase console. Whitelisting phone numbers provides these benefits:. You can directly start using a whitelisted phone number in your application.

This allows you to perform manual testing during development stages without running into quota issues or throttling. When you provide the whitelisted phone number and send the verification code, no actual SMS is sent. Instead, you need to provide the previously configured verification code to complete the sign in. On sign-in completion, a Firebase user is created with that phone number. The ID token minted during this process has the same signature as a real phone number user.

Another option is to set a test role via custom claims on these users to differentiate them as fake users if you want to further restrict access. In addition to manual testing, Firebase Authentication provides APIs to help write integration tests for phone auth testing. This makes automation testing possible in these flows and easier to implement.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Both provide a different workflow to tie it best into your app; signInWithPhoneNumber will sign the user in automatically once the user had confirmed their phone number, whilst verifyPhoneNumber will provide feedback on the current verification state but requires you to manually sign the user in once confirmed.

However Android also provides "auto verification" if Google Play service can automatically detect the incoming message and doesn't display it! It is of particular use if you want to link a phone credential with an existing account rather than just sign the user in. Skip to content.

To get started, you must first setup a Firebase project and install the "app" module. They are here. React Native Firebase is the officially recommended collection of packages that brings React Native support for all Firebase services on both Android and iOS apps.

Authentication Methods

Before getting started, the documentation assumes you are able to create a project with React Native and that you have an active Firebase project. If you do not meet these prerequisites, follow the links below:. If you're starting a fresh React Native project, you can take advantage of the template for React Native Firebase:.

To allow the Android app to securely connect to your Firebase project, a configuration file must be downloaded and added to your project. On the Firebase console, add a new Android application and enter your projects details.

The debug signing certificate is optional to use Firebase with your app, but is required for Dynamic Links, Invites and Phone Auth. This generates two variant keys. Download the google-services. To allow Android to validate the credentials, the google-services plugin must be enabled on the project. This requires modification to two files in the Android directory. To allow the iOS app to securely connect to your Firebase project, a configuration file must be downloaded and added to your project.

On the Firebase console, add a new iOS application and enter your projects details. Download the GoogleService-Info. Right click on the project name and "Add files" to the project, as demonstrated below:.

Select the downloaded GoogleService-Info. Within the didFinishLaunchingWithOptions method, add the configure method:. Once the above steps have been completed, the React Native Firebase library must be linked to your project and the app needs to be rebuilt. Users on React Native 0. To automatically link the package, rebuild your project:.

This module does not provide much functionality, therefore to use other Firebase services the modules need installing separately. If you're using an older version of React Native without autolinking support, or wish to integrate into an existing project, you can follow the manual installation steps for iOS and Android.

As your application starts to grow with more native dependencies, your builds may start to fail with the common Execution failed for task ':app:mergeDexDebug' error. This error occurs when Android reaches the 64k methods limit. One common solution is to enable multidex support for Android.

Authenticate with Firebase with a Phone Number Using JavaScript

This is a common solution to solving the problem, however it is recommended you read the Android documentation to understand how it may impact your application. We are actively tracking the changes to Hermes and will ensure support once both are compatible with each other. Each release of the library is tested against a fixed set of SDK versions e. Firebase SDKsallowing us to be confident that every feature the library supports is working as expected. Sometimes it's required to change these versions to play nicely with other React Native libraries; therefore we allow manually overriding these native SDK versions.

Using your own SDK versions is generally not recommended as it can lead to breaking changes in your application.
