Description

This pull request implements a production-ready, secure password reset feature across the backend authentication flow.
It introduces the necessary database changes, API endpoints, validation, services, configuration, and comprehensive documentation, with a strong focus on security, maintainability, and real-world deployment readiness.


Key Changes

🔐 Password Reset Implementation

  • Added resetPasswordToken and resetPasswordExpire fields to the User model and corresponding TypeScript interfaces, with secure defaults and exclusion from default queries.
  • Implemented the following endpoints with full validation and security controls:
    • POST /api/v1/auth/forgot-password
    • POST /api/v1/auth/reset-password/:token
  • Introduced password-reset.service.ts for core reset logic and email.utils.ts for sending secure, HTML-formatted reset emails.
  • Email delivery supports both Gmail and custom SMTP providers.

🛡️ Security and Validation Enhancements

  • Enforced strong password requirements.
  • Implemented cryptographically secure reset tokens:
    • 256-bit entropy
    • SHA-256 hashing
    • 15-minute expiry
    • Single-use enforcement
  • Prevented user enumeration via consistent, user-safe error messages.
  • All sensitive details are logged server-side only.
  • Used Zod schemas for strict input validation with clear, user-friendly errors.

⚙️ Configuration and Documentation

  • Added and documented all required environment variables for email delivery and frontend integration.
  • Included detailed documentation for usage, setup, security, and troubleshooting:
    • IMPLEMENTATION_SUMMARY.md
    • PASSWORD_RESET_API.md
    • AUTHENTICATION_API.md
    • SETUP_GUIDE.md

✅ Code Quality and Readiness

  • Fully typed TypeScript implementation.
  • Clean separation of concerns with modular, reusable services.
  • Aligned with existing project architecture and production best practices.
  • Designed for extensibility and long-term maintenance.

How to Test

  1. Configure environment variables as described in SETUP_GUIDE.md
  2. Start the server
  3. Call POST /api/v1/auth/forgot-password with a registered email
  4. Use the received token with POST /api/v1/auth/reset-password/:token
  5. Verify that the password is updated and the token is invalidated

Summary of Changes

Hello @rdx-exe, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request delivers a robust and secure password reset functionality for the backend. It integrates new database fields, API endpoints, and dedicated services to manage the entire password reset lifecycle, from token generation and email dispatch to password update and token invalidation. The implementation prioritizes security, user privacy, and ease of configuration, complemented by thorough documentation to facilitate understanding and future maintenance.

Highlights

  • Secure Password Reset Feature: Implemented a comprehensive and secure password reset feature, including new database fields, API endpoints, and dedicated services for handling reset logic and email notifications.
  • Enhanced Security Measures: Introduced strong security practices such as cryptographically secure token generation (256-bit entropy), SHA256 hashing for stored tokens, 15-minute token expiry, one-time token use, and strong password requirements with bcrypt hashing.
  • Comprehensive Documentation: Provided extensive documentation across multiple new Markdown files, covering system architecture, implementation details, API specifications, setup guides, security considerations, and testing procedures.
  • Improved User Experience & Privacy: Ensured user-safe error messages that do not expose sensitive details, and implemented email enumeration protection by always returning a generic success message for forgot password requests.
  • Configurable Email Service: Developed an email utility that supports both Gmail and custom SMTP configurations for sending HTML-formatted password reset emails, with environment variables for easy setup.

Code Review

This pull request introduces a comprehensive and secure password reset feature, complete with backend logic, frontend components, and extensive documentation. The backend implementation is robust, following security best practices like using cryptographically secure tokens, hashing them for storage, setting expirations, and preventing email enumeration attacks. The separation of concerns into services and utilities is well-executed. However, there are several inconsistencies in the documentation that need to be addressed to avoid confusion. More critically, the new frontend component for handling the password reset flow is fundamentally mismatched with the backend's link-based implementation, as it's designed for a code-based verification flow. This will need to be redesigned to work correctly.

critical

The UI flow implemented in this component is fundamentally mismatched with the backend's password reset logic. This component is designed for a multi-step process involving a 'verification code' (step state with 'email', 'verification', 'reset').

However, the backend implements a link-based flow:

  1. User submits their email.
  2. Backend sends an email with a unique URL like .../reset-password/:token.
  3. User clicks the link, which takes them to a new page to enter and confirm their new password.

There is no 'verification code' step. This component will not work with the backend as is. It needs to be redesigned to support the link-based flow. This likely involves:

  • This component handling only the initial email submission.
  • A new, separate component for the /reset-password/:token route that reads the token from the URL and presents the form to enter a new password.

high

The documentation for the forgot-password endpoint's error response is misleading. It shows a 400 Bad Request with an error message. While this can happen for malformed input, a key security feature of this endpoint is that it always returns a success message for validly formatted requests (even if the email doesn't exist or an internal error occurs) to prevent email enumeration. The documentation should be updated to clarify this behavior, as it's a critical aspect of the API's security design.

In the System Architecture diagram, the route for the Reset Password Page is listed as /reset-password/:id. For consistency with the implementation and other documentation, this should be /reset-password/:token since the API uses a token, not a user ID, in the URL.

The file structure diagram is inaccurate. It lists user.service.ts, user.utils.ts, and user.middleware.ts under the src/api/v1/user/ directory. However, the project structure places services in src/services/ and utilities in src/utils/. Please update the diagram to reflect the correct file locations to avoid confusion for developers.

The file structure diagram in this guide is inconsistent with the actual project structure. It incorrectly places user.model.ts, user.type.ts, etc., inside the user directory, and also misplaces other files. Please update the diagram to accurately represent the file locations as implemented in the codebase to prevent confusion during setup and development.
