Passport.js

Passport is authentication middleware for Node.js. It is designed to serve a unique purpose: authenticate requests. It delegates all other details (user handling, sessions) to the application.

When to Use

• Node.js/Express Apps: The de-facto standard for Express auth.
• Multiple Strategies: Supporting Local (Username/Password), Google, Facebook, and Twitter login all in one app.
• Legacy/Established Codebases: widely used in existing Mean/Mern stacks.

import passport from "passport";
