7 Essential Nest.js Authentication Libraries for Secure Web Application

Nest.js/jwt makes it easier to generate, verify, and manage JSON Web Tokens (JWTs). It enables secure, token-based authentication. 

• It offers guards and decorators to protect routes. JWT tokens enhance app security. 
• nestjs/oauth makes it easy to integrate with OAuth2 providers, like Google or Auth0. It lets users authenticate using their existing credentials from these platforms. 
• It supports many OAuth2 grant types. It provides decorators and guards to protect routes based on OAuth tokens. 
• nestjs/cookie-session enables session-based authentication using HTTP cookies. It offers middleware for managing session cookies. 
• It allows for configurable session settings. These include cookie end and security flags. They enhance user session management in Nest.js applications. 

Users use these libraries together. They help developers add authentication features. The features ensure the confidentiality, integrity, and availability of web applications. They foster user trust in their security.
