Securing ASP.NET Core with OAuth2 and OpenID Connect
In this course you’ll learn how to secure your ASP.NET Core web applications and APIs with today’s de facto standards: OAuth2 and OpenID Connect.
What you'll learn
You've built a web application, an API, or both with ASP.NET Core, but... something seems to be missing: almost all applications need to be secured these days.
In this course, Securing ASP.NET Core with OAuth2 and OpenID Connect, you'll learn how to use today's standards, OAuth2 and OpenID Connect, to secure ASP.NET Core web applications and APIs.
You’ll learn what these standards are and how to implement them. After that, you’ll learn about authorization and authorization policies, storing your users and integrating with other identity providers. Finally, you’ll learn how to get ready for production and deploy your identity provider.
After this course you'll know the ins and outs of securing ASP.NET Core web applications and APIs with OAuth2 and OpenID Connect.
