// authenticate a user with a email + password

}

case class UserForm(email: String, password: String) extends Authenticatable

// a login attempt is typically a POST request (SSL) to an endpoint `/api/v1/user/login` with `email` + `password`

for {
  (email, pass) <- dataStream
  uf <- UserForm(email, pass)
