OAuth 2.0 has become the industry standard for providing secure access to web APIs, allowing applications to access users' data without compromising security. Companies around the world add OAuth to their APIs to enable secure access from their own mobile apps and third-party IoT devices and even access to banking APIs.

Security expert Aaron Parecki breaks down each of the OAuth flows (grant types) and applies them to use cases such as implementing OAuth for web apps, native apps, and SPAs. In addition to learning how applications can use OAuth to access APIs, you’ll learn how to use OpenID Connect to get the user’s identity.

If you're building an API, you'll learn the differences and tradeoffs between different access token formats, how to choose an appropriate access token lifetime, and how to design scopes to protect various parts of your APIs.

This course includes the latest recommendations from the OAuth working group including covering everything from using PKCE for all types of applications to explaining the motivations behind dropping the Implicit and Password grants from the spec. These security recommendations and more will be rolled up into the new OAuth 2.1 update, so this course will give you an excellent head start on learning the best way to use OAuth going forward!

By the end of this course, you’ll understand:

The problems OAuth was created to solve

The basics of OAuth 2.0 and OpenID Connect

Best practices for developing web-based and native OAuth apps

The difference between local and remote access token validation

How to validate JWT access tokens

And you’ll be able to:

Implement an OAuth client from scratch

Protect the OAuth flows in native and JavaScript apps

Use OpenID Connect to get the user’s name email address

Protect an API with OAuth access tokens

Design scopes to protect various parts of your API
