Answer 1

You do not mention your installation steps. Presume you did the following:

composer require laravel/passport

Register the service provider inside config/app.php

Laravel\Passport\PassportServiceProvider::class,

Run the migrations

php artisan migrate

Lastly generate the keys using

php artisan passport:install

Answer 2

Laravel PassPort uses oauth2 which uses an asymmetric encryption algorithm. So you have to generate the public and private keys. You just have to type this command in your Laravel project to generate these keys. They will be in the storage folder.

php artisan passport:keys

For more information, see the laravel document. Laravel Doc : https://laravel.com/docs/8.x/passport#password-grant-tokens

Another solution is to go to the .gitignore file and delete the ***

storage / *. Keys

*** line before pushing to github
