auth:admin not working - laravel

Question

i have created admin login system but on auth::attempt its always returning false
here is my code
$credentials= ['email' => $request->get('email'), 'password'=>$request->get('password')];
if (Auth::guard('admin')->attempt($credentials)) {
return redirect()->intended(route('admin.dashboard'));
}
in Admin model
<?php
namespace App\Models;
use Illuminate\Foundation\Auth\User as Authenticatable;
class Admin extends Authenticatable
{
protected $guard = 'admin';
protected $primary_key = 'admin_id';
protected $table = 'admins';
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'admin_firstname', 'admin_lastname', 'email', 'admin_username', 'admin_phone', 'admin_picture', 'admin_gender', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
}
in auth.php
'guards' => [
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
auth::attempt is failing dont know why its not working
its logging but problem is found in admin middleware
$this->middleware('auth:admin');
my auth.php
'guards' => [
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
],
],
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\Models\User::class,
],
'admins' => [
'driver' => 'eloquent',
'model' => App\Models\Admin::class,
],
],

Answer 1

your code looking like good.you need to make sure.did you use bcrypt() in registration.like this
$password=bcrypt($request['password']);
and you need to change in config/auth.php
your guard should be like this
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
],
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
'admin-api' => [
'driver' => 'token',
'provider' => 'admins',
],
],
and provider should be
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\User::class,
],
'admins' => [
'driver' => 'eloquent',
'model' => App\Admin::class,
],
],
and password
'passwords' => [
'users' => [
'provider' => 'users',
'table' => 'password_resets',
'expire' => 60,
],
'admins' => [
'provider' => 'admins',
'table' => 'password_resets',
'expire' => 15,
],
],
this is demonstration change your model and driver accordingly
