令牌于一周后过期，届时，用户身份验证就会失败。只有再次登录，才能获得新的令牌。如果用户（或第三方）篡改令牌的过期时间，因为签名不匹配会导致身份验证失败。

如需深入了解 JWT 令牌，了解它的工作方式，请参阅 <a href="https://jwt.io/" class="external-link" target="_blank">https://jwt.io</a>。

## 安装 `PyJWT`

安装 `PyJWT`，在 Python 中生成和校验 JWT 令牌：

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

Você pode implantar sua aplicação FastAPI no <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a> com um **único comando**; entre na lista de espera, caso ainda não tenha feito isso. 🚀

## Login { #login }

Certifique-se de que você já tem uma conta no **FastAPI Cloud** (nós convidamos você a partir da lista de espera 😉).

Depois, faça login:

```console
$ fastapi login
