How to do achieve delegated authentication and authorisation

[sasikumarchenni]

Hi All,

Here is the scenario for me,

I have an application-1logged in using OAUTH Flow (active accesstoken and refresh token).

Application 1 Scope (app1 & app2)

When user moving from application 1 to application 2, application-2 must allow user without authentication.

How do I achieve this use case ? we are not convenient to pass access token from app-1 to app-2. Any solution we can use of ?

I am sure this scenario handled by many of you. please provide your ideas.

thanks
