Using React Native authentication to verify user identity is a relatively painless and simple process that not only protects your organization's data and your users' privacy, but also improves the user experience.

licenseis a key aspect of any app or service these days because it allows the app to determine who the user is and what actions they are allowed to perform.

React Native authentication is the process of verifying the user's identity in a React Native application. This is typically done by asking the user for credentials, such as a username and password, and then checking those credentials against a database of authorized users.

React Native authentication is typically implemented using OAuth 2.0, which allows users to log in through popular third-party services such as Google, Facebook, or Twitter. There are several libraries you can use to implement authentication in React Native - three of which we'll cover in this article.

(Video) React Native Practical Guide(2021 Edition) - Tutorial 1 -Introduction to React Native

Why is React Native authentication important?

React Native authentication is essential because it provides users with a secure way to access protected resources in a React Native application. Without proper user authentication, anyone can access sensitive information or perform actions they shouldn't be able to.

React Native authentication is important for:

  • Protection of sensitive data.Authentication ensures that only authorized users can access sensitive information such as personal information, financial information or confidential business information.
  • improve security.By requiring user authentication, SaaS applications can better protect against unauthorized access, hacking, and other security threats.
  • Improving user experience.Authentication allows the application to customize the user experience and provide relevant content or services based on the user's identity.
  • Supports compliance.In some cases, approval is required by regulations or standards, such as B. HIPAA for healthcare applications, required to protect sensitive data.

Implementing React Native authentication with OAuth2

OAuth2is an open authentication standard commonly used to allow users to access resources without sharing credentials. In the context of React Native authentication, OAuth2 is typically used to allow a user to log into an application using their existing credentials from a third-party service such as Google, Facebook, or Twitter.

The usual flow for OAuth2 in a React Native app is for the user to click the "Login with X" button, which then redirects them to the third-party service's login page. After a user signs in to a third-party service, they are redirected back to the React Native app, where they grant the app permission to access their resources.

Redirects are an important part of the OAuth2 flow in React Native apps. Redirects are used to redirect the user to the login page of the third-party service and then back to the React Native application after the user has logged in. These redirects are typically implemented using the React Native WebView component, which is used to display web pages in a mobile application.

What is Proof of Key Exchange or PKCE?

Proof of Key Code Exchange (PKCE) is an extension of the OAuth2 authorization code flow that provides additional security for public client applications. In the standard OAuth2 authorization code flow, the authorization code is exchanged for an access token. This can lead to security vulnerabilities because a malicious actor can intercept the authorization code and use it to obtain a token to access the user's resources.

PKCE solves this problem by adding an extra step to the authorization code flow where a verification code is generated and sent along with the authorization code. A code verifier is then used to verify the authorization code when exchanging it for an access token, providing an additional layer of security.

React Source authentication libraries

There are a number of different libraries that you can use to implement authentication in your React Native apps. The three discussed here are just some of the possible options - there are many more libraries you can use to implement authentication in React.

Respond to the app's native authentication

Respond to the app's native authenticationis an open source library for implementing authentication in React Native applications using OAuth 2.0 and OpenID Connect. It provides a set of tools and APIs to interact with OAuth 2.0 and OpenID Connect compliant identity providers such as Google, Facebook, and Microsoft to authenticate users.

React Native App Auth supports both Android and iOS platforms and can be easily integrated into a React Native app to perform authentication tasks such as user login and logout, secure authentication token storage, and access token updates.

(Video) Best React Native Course Review | React Native - The Practical Guide

The library abstracts the details of the underlying authentication protocol, making it easy for developers to implement authentication in their applications without dealing with the complexity of the underlying protocols.

reactor navigation

reactor navigationis a popular library for navigating React Native apps. Provides tools and APIs for navigating between screens, managing navigation history, and configuring navigation headers.

React Navigation can be used in conjunction with a separate authentication library to implement authentication in a React Native application by controlling the navigation flow based on authentication status.

Respond to native OAuth

Respond to native OAuthis a library for adding OAuth authentication to React Native applications. With React Native OAuth, developers can add OAuth authentication to their applications and communicate with OAuth-compliant identity providers such as Google, Facebook, and Microsoft to authenticate users. The library includes a set of APIs and tools to handle common OAuth tasks, such as obtaining and updating access tokens, securely storing tokens, and handling token expiration.

React Native OAuth supports both Android and iOS platforms and can be easily integrated into a React Native application to perform authentication tasks.

Example of React Native authentication

Here's an example of using the React Native App Auth library to implement OAuth 2.0 authentication in a React Native app.

First, install the React Native App Auth library:

npm i respond-native-app-auth

Import the React Native App Auth module for your React Native app:

import {authorize, logout} iz 'react-native-app-auth';

Add a function to handle during authorization:

const handleAuthorize = async () => {prøv {const result =waitauthorize({issuer: 'https://VAS_PRIJENOSNIK',clientId: 'YOUR_CLIENT_ID',redirectUrl: 'DIN_REDIRECT_URI',scopes: ['openid', 'profile', 'e-mail'],serviceconfiguration: {authorizationEndpoint: 'https://VAŠA_AUTHORIZATION_ENDPOINT',tokenEndpoint: 'https://YOUR_TOKEN_ENDPOINT',},});console.log(result);} Catch (fejl) {console.error(error);}};

Add a logout function:

(Video) The Practical Guide for React Native 2021 | React Native Tutorial for Beginners | React Native 2021

const handleSignOut = async () => { try {await signOut(options); console.log('Benutzer abgemeldet'); } Catch (greška) {console.error(error);}};

Use the above features in your React Native app to authenticate and log out users.

End-user data and privacy protection is critical in today's business environment. Not only does this prevent costly breaches and reputational damage, but it also improves the customer experience and ultimately helps increase customer loyalty and satisfaction. Using React Native authentication to verify user identity is a relatively painless and simple process that provides organizations with a strong layer of defense for their key users.
