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

#### 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.

But you cannot convert from the gibberish back to the password.

`.add_task()` recebe como argumentos:

- Uma função de tarefa a ser executada em segundo plano (`write_notification`).
- Qualquer sequência de argumentos que deve ser passada para a função de tarefa na ordem (`email`).
- Quaisquer argumentos nomeados que devem ser passados ​​para a função de tarefa (`mensagem = "alguma notificação"`).
