Authenticate with Firebase using C#

To authenticate with Firebase using C#, you can follow the steps below:

1. Create a Firebase project and configure it for your C# application.
2. Install the Firebase Authentication SDK for C# using NuGet package manager.
3. Import the necessary namespaces in your C# code:

using Firebase.Auth;

4. Import the necessary namespaces in your C# code:

FirebaseAuth auth = FirebaseAuth.DefaultInstance;

5. Authenticate using one of the available methods:

• Email and Password authentication:

string email = "user@example.com";
string password = "password123";
auth.SignInWithEmailAndPasswordAsync(email, password).ContinueWith(task => {
  if (task.IsCanceled) {
    Debug.LogError("SignInWithEmailAndPasswordAsync was canceled.");
    return;
  }
  if (task.IsFaulted) {
    Debug.LogError("SignInWithEmailAndPasswordAsync encountered an error: " + task.Exception);
    return;
  }

  FirebaseUser user = task.Result;
  Debug.LogFormat("User signed in successfully: {0} ({1})", user.DisplayName, user.UserId);
});

• Google authentication:

GoogleAuthProvider authProvider = new GoogleAuthProvider();
auth.SignInWithCredentialAsync(authProvider.GetCredential(googleIdToken, googleAccessToken)).ContinueWith(task => {
  if (task.IsCanceled) {
    Debug.LogError("SignInWithCredentialAsync was canceled.");
    return;
  }
  if (task.IsFaulted) {
    Debug.LogError("SignInWithCredentialAsync encountered an error: " + task.Exception);
    return;
  }

  FirebaseUser user = task.Result;
  Debug.LogFormat("User signed in successfully: {0} ({1})", user.DisplayName, user.UserId);
});

Other authentication methods like Facebook, Twitter, GitHub, etc. are also available and can be used in a similar way.

Note: Make sure to handle errors and exceptions appropriately in your code.

That’s it! You have successfully authenticated with Firebase using C#.

Thanks.
