Auth Attempt with guard passes but doesnt login

I created a new model "Chains" to which I extend it as Authen . I created Guards and Providers. When I attempt to login it using Auth::guard('web_chain')->attempt($credentials) it passes but doesnt login the user?

Chains.php (model):

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Chain extends Authenticatable
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

Auth (config):

'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'api' => [
            'driver' => 'token',
            'provider' => 'users',
            'hash' => false,
        ],
        'web_chain' => [
            'driver' => 'session',
            'provider' => 'chains',
        ],
    ],

 'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\Models\User::class,
        ],

        'chains' => [
            'driver' => 'eloquent',
            'model' => App\Models\chain::class,
        ],

    ],

Login using a Livewire component:

 public function login()
    {
        $credentials = $this->validate([
            'email' => 'required|email',
            'password' => 'required',
        ]);

        if (Auth::guard('web_chain')->attempt($credentials)) {

            return redirect('/wholesale/dashboard');
       } else {

            $this->dispatchBrowserEvent('notify', 'Email and password are wrong.');
        }
    }

I even tried loggin in a user like this, which works but also logs in the first user in the table Users as well?

if(Auth::guard('web_chain')->attempt($credentials)) {

            $user = Chain::where('email', '=', $credentials['email'])->first();

            Auth::login($user);

            return redirect('/wholesale/dashboard');
        }
