Our application consists of 2 components: web site for user registration and window service to process their accounts.
User will register with web site to register his email address. During registration, we authenticate user using oauth and stores his access token and refresh token.
Once user register, window service starts using access token etc and try to validate credential using access token or refresh token but it doesn't work. just for more clarity, web site and window service runs on 2 different machine.
How we can use same access token or refresh token through window service without user interaction?
