In this course,

you'll learn how you can build

a React driven prompted applications,

user interfaces running in the browser, powered by React.

Now, many of those web applications

which you are going to build

will actually need authentication DOM.

You will often have certain areas in your websites

and your web apps

that require users to sign up and log in.

And therefore that is exactly

what we're going to take a first look at

in this course section.

Because in this course section

I'll introduce you to authentication in react apps.

I'll explore how authentication generally works

in such React apps.

We are going to implement an example

for user authentication.

We're going to implement sign up and log in and log out

and we're going to learn

how we can then also access protected resources

once the user is logged in.

And we're also going to explore the important topics

of authentication persistence,

so that users stay logged in

even if they leave your page.

And we're going to have a look at logging users out

automatically after some time.

That's all packed into this module

and therefore let's now dive right in

and let's understand how authentication works

before we then see a concrete example and write some code.
