To use NPM, you don’t need an account, but you’ll need one to publish your own packages. We’ll create a package with simple functionality in this course. Later, we’ll learn about publishing details such as versions and tags.

We’ll start with the external project and extend it by the login page. We’ll also learn how to create password verification functionality and allow users to sign in, sign out and sign up.
