Os servidores DNS iriam informar o navegador para utilizar algum **endereço IP** específico. Esse seria o endereço IP público em uso no seu servidor, que você configurou nos servidores DNS.

### Início do Handshake TLS

O navegador então irá comunicar-se com esse endereço IP na **porta 443** (a porta HTTPS).

# Security - First Steps { #security-first-steps }

Let's imagine that you have your **backend** API in some domain.

And you have a **frontend** in another domain or in a different path of the same domain (or in a mobile application).

And you want to have a way for the frontend to authenticate with the backend, using a **username** and **password**.

We can use **OAuth2** to build that with **FastAPI**.

# First Steps { #first-steps }

The simplest FastAPI file could look like this:

{* ../../docs_src/first_steps/tutorial001.py *}

Copy that to a file `main.py`.

Run the live server:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

+ If you're planning to implement a new feature, it makes sense to discuss your changes
  on the [dev list](https://maven.apache.org/mailing-lists.html) first.
  This way you can make sure you're not wasting your time on something that isn't
  considered to be in Apache Maven's scope.
+ Submit a ticket for your issue, assuming one does not already exist.
  + Clearly describe the issue, including steps to reproduce when it is a bug.

Claro, há alguns casos em que não há problema em executar as etapas anteriores várias vezes; nesse caso, é muito mais fácil de lidar.

/// tip | Dica

Além disso, tenha em mente que, dependendo da sua configuração, em alguns casos você **pode nem precisar de nenhuma etapa anterior** antes de iniciar sua aplicação.

Nesse caso, você não precisaria se preocupar com nada disso. 🤷
