Reset Firebase User Password in C# Using Firebase SDK

In this guide, we'll walk through the process of resetting a user's password in a C# application using the Firebase SDK. This functionality is essential for providing a smooth user experience, allowing users to recover their accounts in case they forget their passwords

Firebase Authentication provides an easy way to integrate user authentication into apps. It supports various sign-in methods like email/password, phone number, and social media accounts. Users can manage their passwords and receive email verification. The service ensures secure authentication and integrates well with other Firebase tools

Set Up Firebase SDK:
Make sure you have the Firebase SDK installed and configured in your C# project. You can add it via NuGet Package Manager.

namespace demo.Services.Implementation
{
    public class Service : IService
    {  
        private readonly FirebaseAuth _firebaseAuth;

        public Service(IHTTPService httpService)
        { 
            _httpService = httpService;

            var FilePath = Path.Combine(Directory.GetCurrentDirectory(), "Firebase/your-json-file-name.json");


         // Check if the default FirebaseApp instance already exists
         if (FirebaseApp.DefaultInstance == null)
         {
             FirebaseApp.Create(new AppOptions()
             {
                 Credential = GoogleCredential.FromFile(FilePath)
             });
         }
            _firebaseAuth = FirebaseAuth.DefaultInstance;
        }

        public async Task resetPassword(string Email, string newPassword)
        {

            var uid = await getUID(Email);

            var userRecordArgs = new UserRecordArgs()
            {
                Uid = uid,
                Password = newPassword,
            };

            await _firebaseAuth.UpdateUserAsync(userRecordArgs);
        }

        public async Task<string> getUID(string email)
        {
            var userRecord = await _firebaseAuth.GetUserByEmailAsync(email);
            return userRecord.Uid;
        }

    }
