Express Framework Fundamentals - Secure Sign-Up with Auth0 and Node.js - Username and Password Local Strategy Code

This video tutorial covers the setup and implementation of user authentication using Passport and Local Strategy in a Node.js application. It begins with installing necessary packages and setting up the authentication process, including username and password verification. The tutorial also addresses error handling and password hashing using crypto. It concludes with testing the login functionality, debugging common errors, and introducing session management with Express.

What is the purpose of installing the passport-local package?

• To enable database connectivity

• To provide local authentication strategy

• To enhance server performance

• To manage user sessions

Which library is used to handle routing in the authentication setup?

• Koa

• Fastify

• Hapi

• Express

What does the local strategy in Passport.js help with?

• Database management

• Username and password verification

• Session storage

• API request handling

Which method is used to access the database in the local strategy?

• To manage user sessions

• To optimize database queries

Which hashing algorithm is mentioned for cryptographic hashing?

• SHA-1

• SHA-256

• SHA-512

• MD5

What is the role of the timingSafeEqual function in the crypto module?

• To manage user sessions

• To compare two strings securely

• To encrypt passwords
