Laravel Mein Authentication Aur Authorization Ka Farq: A Complete Guide in Hindi

🔐 Authentication Kya Hai?

Authentication ka matlab hota hai user ki identity verify karna. Jab koi user login karta hai, toh system yeh check karta hai ki uske dwara diya gaya email aur password valid hai ya nahi.

Laravel mein authentication kaafi aasan hai. Laravel built-in Auth system ke through session-based authentication provide karta hai.

✅ Example: User Authentication in Laravel

php
if (Auth::attempt(['email' => $email, 'password' => $password])) {
    // Authentication passed...
    return redirect()->intended('dashboard');
}

Agar credentials sahi hain, Laravel ek session create karta hai jise future requests ke liye use kiya jata hai.

✅ Authorization Kya Hai?

Authorization ka matlab hai ye decide karna ki ek authenticated user ko kin cheezon ka access hai. Yani ek baar user login ho gaya, tab system check karega ki user kya-kya actions perform kar sakta hai.

Laravel mein authorization implement karne ke liye do major tools hote hain:

• Policies – Specific model actions ke liye.

• Gates – General purpose logic ke liye.

✅ Example: Policy Use Karna

php
public function update(User $user, Post $post)
{
    return $user->id === $post->user_id;
}

✅ Example: Gate Define Karna

php
Gate::define('update-post', function ($user, $post) {
    return $user->id === $post->user_id;
});
