[Cosmic JS](https://cosmicjs.com/) is a modern, headless content management system that empowers teams to build apps faster, together. Cosmic JS provides a web-based dashboard for content creators to manage content, and API tools and resources for developers to integrate their content with their applications.\n\nIn this tutorial I’ll demonstrate using the Cosmic JS CLI to install an [Angular Authentication App](https://cosmicjs.com/apps/angular-authentication-app), built by [Ankit Kumar](https://cosmicjs.com/a9kitkumar) in the [Cosmic Community](https://cosmicjs.com/community) using Angular 6, Node.js and Cosmic JS. Users can register with their email address or their Google Login, with all data stored in Cosmic JS. I encourage you to read the [original article](https://cosmicjs.com/articles/how-to-build-an-authentication-app-using-angular-6-and-cosmic-js) to see how it’s built. You can install, deploy and edit every part of this Angular Auth App from your Cosmic JS Bucket Dashboard. 🔥\n\n### TL;DR:\n\n[Angular Authentication App](https://cosmicjs.com/apps/angular-authentication-app) \n[Angular Authentication App Demo](https://cosmicjs.com/apps/angular-authentication-app/demo) \n[Angular Authentication App Codebase](https://github.com/cosmicjs/angular-auth) \n[How to Build an Authentication App using Angular 6 and Cosmic JS](https://cosmicjs.com/articles/how-to-build-an-authentication-app-using-angular-6-and-cosmic-js)\n\n!(https://hackernoon.com/hn-images/0*ZkcXg9cPY7GL6PiX.png)\n\n### Step 1: Create an Account\n\n[**Sign up**](https://cosmicjs.com/signup) **for Cosmic JS + Install the** [**Cosmic CLI**](https://github.com/cosmicjs/cosmic-cli) **+ Create a New Bucket**\n\n[**cosmicjs/cosmic-cli** \n_The official command line tool for Cosmic JS.

Run `cosmic [command] -h` for details on options for a specific command. You're now up and running with an Angular Authentication App that can register users via email or their Google Login, with all content managed entirely from your Cosmic JS Bucket Dashboard and Command Line Terminal tool of choice.\n\n### Conclusion\n\nI was able to easily install an Angular Authentication App using a headless CMS API that I can now use to manage dynamic content changes. When ditching the installed content management system and going API-first isn’t quick enough, check out the [Starter Apps](https://cosmicjs.com/getting-started) from Cosmic JS to get a project up and running in seconds. 🔥\n\nLearn more about [contributing your own project](https://cosmicjs.com/contribute) to the Cosmic JS Community.
