Laravel Cloud is a new platform that simplifies deployment and management of Laravel applications in a scalable, serverless environment. To deploy an enterprise-ready authentication system, users can set up a Laravel 12 project with WorkOS AuthKit, leveraging zero-config hosting and features like social logins, passkeys, Magic Auth, and SSO. The guide outlines six steps to complete the setup: installing Laravel 12 with WorkOS AuthKit, configuring WorkOS in Laravel, setting up redirects in WorkOS, choosing authentication methods, syncing the AuthKit session timeout, and deploying to Laravel Cloud. By following these steps, users can quickly add enterprise-grade authentication features to their Laravel applications, saving time and development effort.
