Website application development brings us many challenges, and one of them is user authentication.
Using Firebase Authentication makes this mission simpler, saves us a significant amount of time, and speeds up code implementation.
Firebase Authentication is one of Firebase's key features. It helps identify our users and manage users’ data quickly and easily.
In this article, we will explore the different sign-in methods available with Firebase Authentication.
Firebase Authentication SDK provides a variety of authentication methods that can be used to authenticate users to our app. Let's take a look at some of the key methods:
Email and Password-Based Authentication
Firebase Authentication SDK, you can easily create and manage users who sign in using their email addresses and passwords.
Furthermore, Firebase Authentication streamlines the password reset process by handling the email notification sent to users requesting a password reset.
With these features, you can focus on developing your app and let Firebase handle user authentication and password reset management.
Federated Identity Provider Integration
Firebase Authentication SDK provides a seamless experience to authenticate users by integrating with federated identity providers like
Phone Number Authentication
You can also authenticate users using a phone number, rather than an email and password.
Firebase Authentication sends a verification code to the user's phone number and, upon confirmation, the user is authenticated.
This feature can help simplify the sign-in process for users who don't have an email account or who prefer not to use it for authentication.
Additionally, it can help prevent fake accounts, since a real phone number is required for authentication.
Custom Auth System Integration
Firebase Authentication SDK provides custom authentication support, which allows you to integrate your app's existing sign-in system with Firebase's secure authentication.
You can use your own authentication process to generate custom authentication tokens that can be used to authenticate users in Firebase.
Cloud Storage, and
Anonymous authentication enables users to access features that require authentication without first logging in.
This is accomplished by setting up temporary anonymous accounts. If the user wishes to sign up later, you can convert the anonymous account to a regular account, allowing the user to pick up where they left off.
At the same time, this can increase user retention and adoption of your app.
In addition to the Firebase SDK authentication methods, there are other options available:
Firebase Authentication with Identity Platform
Firebase Authentication with Identity Platform is a powerful upgrade that brings additional features.
With enhanced logging and enterprise-grade support and SLAs, you can improve your app's user authentication and security.
However, it's important to note that Firebase Authentication with Identity Platform has a different pricing scheme than the base product, so make sure to review the billing implications before upgrading.
Firebase Authentication provides support for Multi-Factor Authentication (MFA), also known as two-factor authentication (2FA), to add an extra layer of security to your app.
With MFA, users have to provide an additional authentication factor, such as a code sent to their phone, to prove their identity before accessing sensitive information.
Firebase Authentication handles the sending and verification of SMS codes, making it simple to integrate MFA into your app.
Blocking functions, often known as hooks, allow you to adjust your app's registration or sign-in flow. You can use these functions to check user data, prevent particular users from signing in, or even build customized two-factor authentication.
The blocking functions run before and after given authentication events based on conditions you specify, such as the user's email domain or IP address.
You can add an extra layer of protection and customization to your app's authentication process by using these services.
Firebase Authentication implements industry-standard OAuth 2.0 and OpenID Connect to identify users.
When a user logs in or signs up with Firebase Authentication, the authentication flow occurs in the following steps:
Getting Authentication Credentials
To sign a user into your app, you first need to get their authentication credentials. This can be their email address and password or an OAuth token from a federated identity provider like
Once you have these credentials, you can pass them to the
Firebase Authentication SDK.
Firebase Authentication SDK then sends the authentication credentials to the Firebase internal backend services, which verify the credentials and return a response to the client.
This response includes a Firebase Authentication token, which is used to manage the user session.
Accessing User Profile Information
Once the user successfully signs in, you can access their basic profile information, such as their name and profile picture.
Additionally, you can use the provided authentication token to verify the user's identity in other backend services. Firebase Authentication also allows you to control the user's access to data stored in other Firebase products.
Controlling User Access to Data
Security Rules allow you to control the access of authenticated users to your data in
Firebase Realtime Database,
Cloud Firestore, and
For example, you can create a rule that allows a user to view data only if they are logged in, or to write data only if certain circumstances are met.
This assists you in protecting sensitive data against unauthorized access or modification.
Firebase Security Rules are built on a robust rules language that lets you describe conditions with variables, operators, and functions. You can test your rules in the Firebase console and monitor their performance to ensure that your data is protected.
My goal with this post was to show why Firebase Authentication is a powerful tool that can simplify the user authentication process in web and mobile app development while speeding up code implementation.
Following industry-standards you can securely and reliably identify users with various sign-in methods, including email and password, federated identity provider integration, phone number authentication, and custom auth system integration.
At the same time, Firebase Authentication also provides other features that further enhance app security and user experience.
This vast set of options gives flexibility and convenience for both developers and users.
