Complete NextAuth course

In this project, we are going to implement the nextauth to our nextauth app. We will go through different provider like email provider, github provider, twitter provider, facebook provider and auth0 provider (which can login with microsoft, amazon, paypal, dropbox ,yahoo and yandex, etc.). In this example, we demonstrate how to login with microsoft account. We will also learn how to setup sendGrid so we can make a passwordless signin with email. Also, we will setup firebase adapter and mongodb adapter, so the users data will store in these database. At last, we will also deploy the app to the Vercel.
