Laravel Passport: API Authentication using Token and Scopes

Most systems nowadays require authentication to access the resources. For API we use tokens to authenticate the users and do not maintain the session state between the requests. Laravel provides the package “Passport” for API authentication, which provides the OAuth2 server implementation for the application.

Below are the steps on how to generate the token using Laravel Passport and how to use token scopes:
