如何自定义laravel登录以添加通用密钥？

Question

how to overwrite laravel's login method, I want to add a universal key, to be able to enter the accounts of system users.

After making the login attempt and if it does not match the credentials of the database, make another attempt with a universal password that is in the code.

I think it is here (EloquentUserProvider) where the validation of credentials is done, but I do not know how to customize it so that it works as I wish.

public function validateCredentials(UserContract $user, array $credentials)
{
    $plain = $credentials['password'];

    return $this->hasher->check($plain, $user->getAuthPassword());
}

I´m usising laravel 5.6

Laravel Fired sendFailedLoginResponse method after failed login. You can overwrite it.

Check AuthenticatesUsers trait in LoginController

protected function sendFailedLoginResponse(Request $request)
{
   if($this->limiter()->attempts($this->throttleKey($request)) == 1){ //if first login attempt failed
      //implement your own login logic here with universal password 

   }else{
      throw ValidationException::withMessages([
        $this->username() => [trans('auth.failed')],
      ]);
   }
}
