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.

`Hero` sınıfı, bir Pydantic modeline çok benzer (hatta altta aslında *bir Pydantic modelidir*).

Birkaç fark var:

* `table=True`, SQLModel’e bunun bir *table model* olduğunu söyler; SQL veritabanında bir **table**’ı temsil etmelidir, sadece bir *data model* değildir (diğer normal Pydantic sınıflarında olduğu gibi).

Python will have to compare the whole `stanleyjobso` in both `stanleyjobsox` and `stanleyjobson` before realizing that both strings are not the same. So it will take some extra microseconds to reply back "Incorrect username or password".
