I am a beginner in laravel .I am using guard for multi authorization. I am having this issue in my admin login:
TypeError
Illuminate\Auth\SessionGuard::login(): Argument #1 ($user) must be of type Illuminate\Contracts\Auth\Authenticatable, App\Models\Admin given, called in C:\Users\DELL\survey\app\Http\Controllers\AdminController.php on line 34

This is the AdminController.php file

<?php



namespace App\Http\Controllers;

use App\Models\Admin;

use Illuminate\Http\Request;

use Illuminate\Support\Facades\Auth;

use Illuminate\Support\Facades\Hash;

use Illuminate\Contracts\Auth\Authenticatable;



class AdminController extends Controller

{

    public function login()

    {

        return view('admin.login');

    }

    public function authenticate(Request $request)

    {

        $request->validate([

            'email' => ['required', 'email'],

            'password' => ['required']

        ]);



        /** @var Admin $model */

        $model = Admin::query()->where('email', $request->get('email'))->firstOrFail();



        if(!$model){

            return back()->with('error', 'Email or password is incorrect');

        }



        if (!Hash::check($request->get('password'), $model->password)) {

            return back()->with('error', 'Email or password is incorrect');

        }



        Auth::guard('admin')->login($model);



        return redirect()->route('dashboard')

            ->with('success', 'Welcome ' . $model->name . '!');

    }

}

This is the login.blade.php

<x-guest-layout>

    <x-auth-card>

        <x-slot name="logo">

            <a href="/">

        <form method="POST" action="{{ route('admin-authenticate') }}">

                                required autocomplete="current-password" />

            </div>



            <!-- Remember Me -->

            <div class="block mt-4">

                    <span class="ml-2 text-sm text-gray-600">{{ __('Remember me') }}</span>

                </label>

            </div>



            <div class="flex items-center justify-end mt-4">

                @if (Route::has('password.request'))

                    <a class="underline text-sm text-gray-600 hover:text-gray-900" href="{{ route('password.request') }}">

                        {{ __('Forgot your password?') }}

                    </a>

                @endif



                <x-button class="ml-3">

                    {{ __('Log in') }}

                </x-button>

            </div>

        </form>

    </x-auth-card>

</x-guest-layout>

How do I fix this?
