Getting Started

Install Passport on fresh or existing Laravel project.

Step 1. Install Laravel

If you have an existing Laravel running project, then you can skip this step. Otherwise, we require to get fresh Laravel application using below command, So open your terminal or command prompt and run command below:

composer create-project --prefer-dist laravel/laravel project_name

Step 2. Install Laravel Passport Package

To get started, install Passport via the Composer package manager:

composer require laravel/passport

Step 3. Run Migration

Firstly, setup your database with project through .env file:

DB_DATABASE=DATABASE NAMEDB_USERNAME=USERNAMEDB_PASSWORD=PASSWORD

Then do the migrations, Passport migrations will create the tables for your application in database that stores clients and access tokens.

php artisan migrate

Step 4. Generate keys

This command will create the encryption keys needed to generate secure access tokens. In addition, the command will create “personal access” and “password grant” clients which will be used to generate access tokens:

php artisan passport:install

Step 5. Passport Config

Add the Laravel\Passport\HasApiTokens trait to your App\Usermodel. This trait will provide a few helper methods to your model which allow you to inspect the authenticated user's token and scopes and HasApiTokens in User class :

<?php
namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Laravel\Passport\HasApiTokens;

class User extends Authenticatable
{
    use Notifiable, HasApiTokens;
}

Next, you should call the Passport::routes method within the boot method of your App/Providers/AuthServiceProvider. This method will register the routes necessary to issue access tokens and revoke access tokens, clients, and personal access tokens. And Add this trait also use Laravel\Passport\Passport;

<?php
namespace App\Providers;

use Laravel\Passport\Passport;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
class AuthServiceProvider extends ServiceProvider
{
    protected $policies = [
        'App\Model' => 'App\Policies\ModelPolicy',
    ];
    public function boot()
    {
        $this->registerPolicies();
        Passport::routes();
    }
}

Finally, in your config/auth.php configuration file, you should set the driver option of the api authentication guard to passport. This will instruct your application to use Passport's TokenGuard when authenticating incoming API requests:

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],
    'api' => [
        'driver' => 'passport',
        'provider' => 'users',
    ],
],

NOTE -In these first five steps, Installation of passport on any Laravel project has been done
