Firebase Authentication vs sso: What are the differences?

Introduction:

Firebase Authentication is a service offered by Google that allows developers to easily add user authentication to their web or mobile applications. On the other hand, SSO (Single Sign-On) is a mechanism that enables users to authenticate and access multiple independent software systems or websites using a single set of credentials.

1. Scalability: Firebase Authentication is highly scalable and can handle a large number of users without any issues. It is designed to handle authentication for millions of users, making it suitable for applications with high user bases. On the other hand, SSO systems may have limitations when it comes to scalability, especially if they are not properly designed for handling a large number of users. They may experience performance issues or fail to provide a seamless user experience in such scenarios.

2. Provider Support: Firebase Authentication supports a wide range of authentication providers, such as email/password, Google, Facebook, Twitter, and more. It provides built-in integrations with these providers, making it easier for developers to implement authentication using these platforms. On the contrary, SSO solutions may have limited provider support. While they may support popular providers like Google or Facebook, they may not have integrations or built-in support for niche providers or custom authentication systems.

3. Integration Complexity: Firebase Authentication offers a simple and straightforward integration process. Developers can easily set up authentication with Firebase by following the provided documentation and using the Firebase SDKs. In contrast, SSO solutions may require additional integration efforts and custom code to enable authentication. The complexity of the integration process may vary depending on the chosen SSO system and the requirements of the application.

4. Centralized User Management: Firebase Authentication provides a centralized user management system where developers can manage and control user accounts. This includes features like user creation, deletion, updating user attributes, and account suspension. SSO systems, on the other hand, rely on the user management systems of the individual software systems or websites. They do not offer a centralized user management interface, which can make it more complicated for administrators to manage user accounts across different systems.

5. Flexibility in User Data: Firebase Authentication allows developers to store and manage additional user data in the Firebase Realtime Database or Cloud Firestore. This means that developers can easily extend the user profiles with custom data and tailor the authentication system to their specific application requirements. SSO systems generally rely on the user data available in the individual software systems or websites and may not provide the same level of flexibility in managing additional user data.

6. Pricing Model: Firebase Authentication offers a free tier that allows developers to authenticate up to a certain number of users without any cost. It also provides paid plans for applications with higher user bases or advanced authentication requirements. SSO systems may have different pricing models and may charge based on factors like the number of users or the features required. The pricing structure of SSO solutions may vary and can be significantly different from Firebase Authentication.

In Summary, Firebase Authentication offers scalability, extensive provider support, easy integration, centralized user management, flexibility in user data, and a flexible pricing model. SSO systems, on the other hand, may have limitations in scalability, limited provider support, complex integration, lack of centralized user management, limited flexibility in user data, and potentially different pricing models.
