A deep dive into production-ready security implementation: automatic TLS certificate management with Let
A comprehensive guide to implementing TOTP-based two-factor authentication in production systems. Covers server-side QR code generation, secure cookie handling with proxy detection, trusted device management, session duration optimization, and audit logging for compliance. Learn from real implementation in the email-server project with code examples from Go.
Authentication is a fundamental aspect of secure API development, allowing you to protect routes and control access to resources. By implementing JWT (JSON Web Tokens) for authentication in a Node.js and Express application, you can achieve stateless and secure access for your users. This guide covers setting up user registration, logging in, generating JWT tokens, and securing routes with JWT-based authentication.

This guide covers setting up user registration, logging in, generating JWT tokens, and securing routes with JWT-based authentication.
While JWTs (JSON Web Tokens) are a secure way to handle authentication, they are often short-lived, with a limited expiration time to reduce security risks if compromised. To maintain user sessions without requiring frequent re-authentication, refresh tokens allow you to renew access tokens safely. This guide walks through implementing refresh tokens in a Node.js application using Express and Mongoose, allowing for secure and scalable session management.
Role-Based Access Control (RBAC) is a powerful method for managing permissions based on user roles within an application. By combining RBAC with JWT (JSON Web Token) authentication, you can control access to specific resources, ensuring that only authorized users can access or modify certain parts of your application.
In production environments, protecting sensitive data is a critical priority for any application, and securing database connections is fundamental to safeguarding user information and ensuring compliance. For Node.js applications, implementing robust database security involves multiple layers, including authentication, encryption, role-based access control, and secure connection management. This guide covers essential strategies for securing your database in Node.js, discussing secure connection setup, data encryption, and best practices for maintaining a strong security posture.
Password reset functionality is essential for any application that requires user authentication. By combining JWT (JSON Web Token) with Nodemailer, you can build a secure password reset process that allows users to reset their passwords without exposing sensitive data. This guide will walk you through implementing a password reset feature in Node.js with Express, Mongoose, and Nodemailer.
Two-Factor Authentication (2FA) is an extra layer of security that requires not only a password and username but also something that only the user has on them, typically a one-time code generated by an app like Google Authenticator. This guide walks you through implementing 2FA in a Node.js application using TOTP, Google Authenticator, and otplib.
Social authentication enables users to log in using accounts from external providers like Google or Facebook, streamlining the authentication process and improving user experience. In this guide, we’ll implement social login in a Node.js application using Passport.js and OAuth to authenticate users with Google and Facebook.
Explore the implementation of Zero-Trust security architecture in cloud native applications. Learn how to establish robust security measures through identity-based access control, network microsegmentation, continuous monitoring, and automated security policies. This comprehensive guide covers practical strategies for implementing Zero-Trust principles in modern cloud environments.
Email verification is essential for securing the registration process in web applications. It ensures that users are genuine and prevents spam or fraudulent sign-ups. By combining JWT (JSON Web Token) with Nodemailer, you can implement email verification efficiently in a Node.js application. This guide will walk you through setting up email verification, covering JWT generation for verification links, sending emails, and verifying users.
