How does laravel Auth controller know which field to encrypt?

Question

Laravel

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
use Auth;
use Illuminate\Support\Facades\Redirect;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

class AuthController extends Controller
{

  use AuthenticatesAndRegistersUsers, ThrottlesLogins;

  
  public function __construct()
  {
    $this->middleware('guest', ['except' => 'getLogout']);
  }


  
  protected function validator(array $data)
  {
    return Validator::make($data, [
      'login' => 'required|max:255',
      'email' => 'required|email|max:255|unique:users',
      'pass' => 'required|confirmed|min:6',
    ]);
  }

  
  protected function create(array $data)
  {
    $user=new User;
    $user->login= $data['login'];
    $user->email=$data['email'];
    $user->pass=bcrypt($data['pass']);
    $user->save();
  }

  public function authenticate(Request $request)
  {	$login=$request->input('login');
    $pass=$request->input('pass');
    $validator = Validator::make($request->all(), [
      'login'=>'required',
      'pass'=>'required'
    ]);
    if ($validator->fails()) {
      return Redirect::to('auth/login')
        ->withErrors($validator)
        ->withInput();
    } else {
      if (Auth::attempt(['login' => $login , 'pass' => $pass ])) {
        return redirect()->intended('home');
      }
      return Redirect::to('auth/login')
        ->withErrors('Wrong login/pass');
    }
  }

}

Everything is standard. But due to the fact that I changed (or not because of this) password to pass and email to login
All the time throws an error. Still, how does it know that pass is the password that is somewhere by default. So this is where the problem lies? and how to solve it then? or all the same, he somehow magically finds out what the password is from this
