User Authentication Endpoint

The video tutorial covers setting up user authentication in a backend application. It begins with creating routes and controllers for user login, followed by handling request data using Postman and middleware. The tutorial then implements authentication logic, including password matching with Bcrypt for security. Finally, it addresses error handling and prepares for generating tokens for accessing private routes.

What is the initial step in setting up the backend authentication route?

• Creating a database

• Setting up user routes and controllers

• Designing the frontend

• Implementing token generation

Which tool is used to mimic form data submission in the tutorial?

• Postman

• GitHub

• Node.js

• Visual Studio Code

What middleware is added to parse JSON data in the request body?

• Express.urlencoded

• Express.json

• By email

What library is used to compare plaintext and encrypted passwords?

• Bcrypt

• Crypto

• JWT

• Passport

Where is the password comparison method implemented?

• In the server.js file

• In the user model

• In the controller

What is returned upon successful user authentication?
