The video tutorial covers the implementation of a local strategy for user authentication, focusing on verifying usernames and passwords. It explains the use of cryptographic hashing for password security and outlines changes to the index logic to prevent unauthorized access. The tutorial concludes with testing the updated code and planning to set up Express sessions in the next lesson.

What is the purpose of cryptographic hashing in the password verification strategy?

• To convert passwords into a different language

• To make passwords longer and more complex

• To store passwords in plain text for easy access

• To ensure passwords are securely stored and not easily accessible

What change is made to the index.js file to prevent unauthorized access to the homepage?

• Adding a new homepage route

• Implementing a check for a valid user session

• Allowing all users to access the homepage

• Removing the login page

Why is it important to reload the Express server after making changes to the code?

• To apply the changes and ensure they take effect

• To delete all previous data

• To increase the server's speed

• To reset the server to its default state

What is the next step after updating the app code for authentication?

• Removing all user data

• Implementing Express sessions

• Creating a new homepage

• Setting up a new database

What is the result of not having an Express session set up?

• Users can access the app without logging in

• Users cannot log in even with correct credentials

• The app will crash

• The homepage will not load
