In this lesson, we introduce the course and what we'll be covering in the course.

In this lesson, we kick off the course by adding the necessary columns for two-factor authentication to the users table while covering what each of them does along the line.

In this lesson, we'll cover how users can enable two-factor authentication. This include generating a secret code as well as a QR code that users needs to scan with their authenticator apps.

This lesson covers how to log in with an authentication code for users who have enabled two-factor authentication.

In this lesson, we are going to cover generating the two-factor recovery codes and we’ll be doing that at the point of enabling two-factor authentication.

In this lesson, we cover how to log in with recovery codes in addition to being able to log in with codes from authenticator apps.

In this lesson, we add a way for users to regenerate their recovery codes which will come in handy if they lost their recovery codes.

To wrap up this course, let's add a way for users to disable two-factor authentication on their accounts.
