!!! warning
    The supporting additional functions are just to demo a possible flow of the data, but they of course are not providing any real security.

## Reduce duplication

Reducing code duplication is one of the core ideas in **FastAPI**.

!!! warning
    As funções adicionais de suporte são apenas para demonstração de um fluxo possível dos dados, mas é claro que elas não fornecem segurança real.

## Reduzir duplicação

Reduzir a duplicação de código é uma das ideias principais no **FastAPI**.

For this simple example, we are going to just be completely insecure and return the same `username` as the token.

!!! tip
    In the next chapter, you will see a real secure implementation, with password hashing and <abbr title="JSON Web Tokens">JWT</abbr> tokens.

    But for now, let's focus on the specific details we need.
