I'm studing IdentityServer4 and I got question. I know that exist jwt token which need for checking token. It checks that token was gotten from trust server. There is access_token which need to authorize in app. How does it work? I get two tokens or jwt contains a access_token as well?
From an Auth Server(The server which issues the JWT token), you will received a JWT Token aka Access_Token. This Auth Server will contains the Secret-Key that can issues an Access-Token.
From a client(Mobile/Web/Console App), you will need to pass this Access_Token in your Request Header to your Resource Server(The server where your resources stored, normally this is your backend server) to request for Resources/Data.
(e.g : Authorization : Bearer <Access_Token>)
Upon receives a request from client,in your Resource Server, you will need to have a Validate JWT function that will validate the JWT Token based on a public-key (Security Algorithm : RSA256, HS256).
