Auth0 vs Firebase: What are the differences?

Auth0 and Firebase are both widely used services for managing authentication and authorization in web and mobile applications. Here are the key differences between them:

  1. Backend Integration: Auth0 focuses on providing authentication and authorization as a standalone service, which means it can be easily integrated with any backend technology or framework. On the other hand, Firebase offers a comprehensive backend-as-a-service (BaaS) solution that includes authentication as one of its many features. This means that Firebase is tightly coupled with its own backend infrastructure and may require more effort to integrate with a non-Firebase backend.

  2. Identity Providers: Auth0 offers a vast array of pre-built identity providers such as social logins (Facebook, Google, etc.), enterprise providers (Azure AD, Active Directory, etc.), and more. This allows developers to easily enable login options for their users. In contrast, Firebase primarily focuses on social logins and Google accounts, limiting the number of pre-built identity providers available out of the box.

  3. Customization: Auth0 provides extensive customization options, allowing developers to tailor the authentication process to their specific requirements. It offers advanced features like custom login screens, password policies, multi-factor authentication, and more. Firebase, while providing some level of customization, is more opinionated and may not offer the same level of flexibility as Auth0.

  4. Scalability and Performance: Auth0 is built to handle authentication at scale and is designed to handle millions of users and requests. It offers global data centers and can be easily scaled to accommodate growing user bases. Firebase, being part of the Google Cloud Platform, also offers high scalability and performance, but it may have some limitations compared to Auth0 when it comes to handling extremely high volumes of authentication traffic.

  5. Pricing Model: Auth0 has a pricing model based on the number of active users, allowing flexibility for organizations to pay based on usage. Firebase, on the other hand, offers a variety of pricing plans that are primarily focused on usage, storage, and additional features. Some organizations may find Auth0's pricing model more suitable for their needs, while others may prefer Firebase's more predictable pricing structure.

  6. Additional Features: While authentication is the core focus of Auth0, it also offers additional features like user management, OAuth and OIDC support, anomaly detection, and more. Firebase, as a complete BaaS solution, offers a wider range of additional features including real-time database, cloud messaging, storage, hosting, and more. This makes Firebase a more all-in-one solution for developers who require a comprehensive suite of cloud services along with authentication.

In summary, Auth0 is a standalone identity-as-a-service solution, providing flexible authentication and authorization services, while Firebase, part of Google Cloud, offers a comprehensive mobile and web development platform with integrated authentication and real-time database services.

Advice on Firebase, Auth0

ReviewonFirebaseFirebase

I started using Firebase over 5 years ago because of the 'real-time' nature. I originally used to use Real Time Database, but now I use Cloud Firestore. I recommend using the Google Firebase PaaS to quickly develop or prototype small to enterprise level web/mobile applications. Since Google purchased Firebase, it has exploded and it growing rapidly. I also find some level of comfort that it is Backed by Google.

Needs adviceonNode.jsNode.jsExpressJSExpressJSReactReact

We are starting to work on a web-based platform aiming to connect artists (clients) and professional freelancers (service providers). In-app, timeline-based, real-time communication between users (& storing it), file transfers, and push notifications are essential core features. We are considering using Node.js, ExpressJS, React, MongoDB stack with Socket.IO & Apollo, or maybe using Real-Time Database and functionalities of Firebase.

Needs advice

Currently, Passport.js repo has 324 open issues, and Jared (the original author) seems to be the one doing most of the work. Also, given that the documentation is not proper. Is it worth using Passport.js?

As of now, StackShare shows it has 29 companies using it. How do you implement auth in your project or your company? Are there any good alternatives to Passport.js? Should I implement auth from scratch?

Detailed Comparison

Firebase
Firebase
Auth0
Auth0

Firebase is a cloud service designed to power real-time, collaborative applications. Simply add the Firebase library to your application to gain access to a shared data structure; any changes you make to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds.

A set of unified APIs and tools that instantly enables Single Sign On and user management to all your applications.

Add the Firebase library to your app and get access to a shared data structure. Any changes made to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds.;Firebase apps can be written entirely with client-side code, update in real-time out-of-the-box, interoperate well with existing services, scale automatically, and provide strong data security.;Data Accessibility- Data is stored as JSON in Firebase. Every piece of data has its own URL which can be used in Firebase's client libraries and as a REST endpoint. These URLs can also be entered into a browser to view the data and watch it update in real-time.;Real-time Synchronization- Firebase takes a new approach to the way data is moved around an app. Rather than using a traditional request & response model, it works by synchronizing data between devices. Whenever your data changes, all clients are immediately notified within milliseconds. The synchronized data is also persisted, allowing new clients to be immediately updated.;First-class Data Security- Traditional applications intermix security code with application code, whereas Firebase treats security as a first-class feature. You define your security policies in one place using a flexible rules language, and Firebase ensures that they are consistently enforced across all parts of your application. Having all your security logic in one place allows for easy auditing and helps you avoid security mistakes. The safety and security of your data is our top priority.;Automatic Scaling- The Firebase API is built from the ground up for performance and scale. Whenever your data changes, Firebase calculates the minimum set of updates required to keep all your clients in sync. In addition, all Firebase API functions are designed to scale linearly with the size of the data being synchronized. More importantly, Firebase handles all of the scaling and operations for you. Your app will scale from its first user to its first million without any code changes.;Servers are Optional- Firebase can provide all of the data storage, control, and transmission needs of most apps. In many cases, Firebase can completely replace your server and server-side code. This means you no longer need to build complicated backend software and can instead focus on your application logic and your customers.
