OpenID Connect is an authentication protocol built on top of OAuth 2.0, which facilitates clients to verify the end-user identity against the authentication performed by an authorisation server. At the same time, it provides methods to transfer the end user information through claims.
In this talk, we will introduce OAuth 2.0/OpenID Connect and IdentityServer followed by how we migrated an existing custom authentication system to OpenID Connect. We will look at patterns of extending and implementing security within IdentityServer.
We will finish off with what's new in IdentityServer 4.
