thank you for the reply.
i looked again the differences between all these authentication modes and i realized that i can not create str8 the auth token since every method of these return to url that need to redirected by a web server …
i am creating now a django local server to handle the redirection but as i said in my main post for me the usage of a 3rd site for authentication token is a backdoor to my account , since i will authorize a site to view and most important manage my account
so for me now there is only one way … find a way to create locally the authentication token or leave the twitch platform
