Mastering MEAN Web Development Expert Full Stack JavaScript (Video 21)

This video tutorial covers securing an app by creating user models and securely storing passwords. It explains the use of JSON Web Tokens (JWT) for authentication and demonstrates how to set up API routes for user actions like signup and login. The tutorial also discusses password hashing strategies, including the use of salt to enhance security. Finally, it shows how to implement JWT for secure user authentication and manage user sessions.

What is the primary purpose of creating users in an app?

• To enhance user interface design

• To improve app performance

• To secure the app by managing access

• To increase app downloads

Which library is used for creating password hashes in the user model?

• JWT

• Bluebird

• Crypto

• Mongoose

What is the role of the 'salt' in password hashing?

• To encrypt the password

• To make password cracking more difficult

• To add flavor to the password

• To make the password longer

What method is used to define routes for user signup?

• PUT

• GET

• DELETE

• POST

In the signup controller, what is the purpose of the 'setPassword' function?

• To hash the user's password

• To delete the user's password

What is a JSON Web Token (JWT) primarily used for?

• Storing user preferences

• Securing data transmission between parties

• Designing user interfaces

• Enhancing app performance

How is a JWT verified and trusted?

• By being hashed

• By being encrypted

• By being stored in a database

• By being digitally signed

What is the purpose of setting an expiration for a JWT?

• To limit its validity period

• To increase its security

• To ensure it is always valid

• To make it last forever

What is the function of the 'validatePassword' method in the login process?

• To delete the password

• To store the password in plaintext

• To compare the hashed password with the stored hash

• To encrypt the password

What does the 'Bluebird.join' function do in the login controller?

• It deletes the user data

• It waits for promises to resolve

• It hashes the password

• It encrypts the password
