Authentication & Authorization: OAuth

Lesson 1 - Authentication vs. Authorization

Learn the difference between the concepts of authentication and authorization and address some major security concerns that developers must protect against when developing a web application. You will learn how OAuth 2.0 makes implementing security easier for developers and users alike by allowing your users to sign in to your applications while keeping all of the security on well-known and trusted OAuth providers. Finally, you will see OAuth 2.0 in action as you make API requests using Google's OAuth 2.0 Playground.

Lesson 2 - Creating a Google+ Sign-In

Learn about the different types of security flows your application can implement. You will see how security can be handled by your server, your user's browser, or both depending on the type of security your application needs. You will then add a Google+ Sign-In to an existing web application and implement a hybridized client/server flow.

Lesson 3 - Local Permission Systems

Add python code to create server-side rules that will constitute a permission system. This system will limit access of the database for each logged in user based on how the developer designs this code. You will add a User model model to your database to store the credentials, such as username, email, and profile picture, collected from the OAuth provider's API.

Lesson 4 - Adding Facebook & Other Providers

Learn to implement multiple OAuth providers on your web application. You will add Facebook Login as an alternative sign in option for your users and understand how to use OAuth provider documentation to add as many providers as you see fit for your application.
