But it's signed. So, when you receive a token that you emitted, you can verify that you actually emitted it.

That way, you can create a token with an expiration of, let's say, 1 week. And then when the user comes back the next day with the token, you know that user is still logged in to your system.

## 0.70.1

There's nothing interesting in this particular FastAPI release. It is mainly to enable/unblock the release of the next version of Pydantic that comes packed with features and improvements. 🤩

### Fixes

### Install `pydantic-settings`

First, install the `pydantic-settings` package:

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

It also comes included when you install the `all` extras with:

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

## CRUD utils

Now let's see the file `sql_app/crud.py`.

In this file we will have reusable functions to interact with the data in the database.

**CRUD** comes from: **C**reate, **R**ead, **U**pdate, and **D**elete.

...although in this example we are only creating and reading.

### Read data

!!! note "Technical Details"
    You could also use `from starlette.testclient import TestClient`.

    **FastAPI** provides the same `starlette.testclient` as `fastapi.testclient` just as a convenience for you, the developer. But it comes directly from Starlette.

!!! tip

            OAuth2 scopes required for the *path operation* that uses this Security
            dependency.

            The term "scope" comes from the OAuth2 specification, it seems to be
            intentionaly vague and interpretable. It normally refers to permissions,
            in cases to roles.
