secure-auth

Implement secure JWT authentication in Express.js by using bcrypt for password hashing, Redis-backed sessions, and JWT refresh tokens with rotation. This pattern provides secure cross-service auth with revocation controls and prevents session fixation.

Add MFA to a Node.js web application using TOTP integration alongside standard login flows. This approach delivers production-ready multi-factor authentication using standard npm packages without requiring external tooling.

Session-based authentication uses server-side storage like Redis with CSRF protections, while token-based authentication uses JWTs with rotation and revocation. Both provide secure user authentication but differ in state management and cross-service scaling.

Set up OAuth integration and password reset flows using standard Node.js and npm packages with common databases. This configuration establishes secure defaults and rotation controls without requiring external tooling beyond standard npm packages.

Redis is recommended for Redis-backed sessions but standard common databases also support secure session handling and token rotation. The implementation prescribes secure defaults and revocation controls across server and client boundaries regardless of storage backend.

Implement password hashing with bcrypt using strong cost factors when building login flows for web, mobile, or API services. This prevents common authentication pitfalls like insecure token storage and session fixation in production environments.
