A variável `oauth2_scheme` é um instância de `OAuth2PasswordBearer`, mas também é um "callable".

Pode ser chamada de:

```Python
oauth2_scheme(some, parameters)
```

Então, pode ser usado com `Depends`.

## Use-o

Agora você pode passar aquele `oauth2_scheme` em uma dependência com `Depends`.

   * exists, a CAS is tried.  Retries proceed by "double hashing",

If the passwords don't match, we return the same error.

#### Password hashing { #password-hashing }

"Hashing" means: converting some content (a password in this case) into a sequence of bytes (just a string) that looks like gibberish.

Whenever you pass exactly the same content (exactly the same password) you get exactly the same gibberish.
