How to force_verify with Twitch Authentication Node Sample?

Akira_Kurusu · October 25, 2020, 10:27am

Im using the Twitch Authentication Node Sample from GitHub (access on 25.10.2020) and want to add the parameter “force_verify” so that the user doesn’t log in automatically. Is this possible and if how?
(I could embed the code here, but it’s on GitHub anyway)

That example uses the passport Twitch strategy.

A brief read of the passportJS docs it seems that it doesn’t support it.

As per my example(s)

github.com

BarryCarlyon/twitch_misc/blob/master/authentication/user_access_generator/nodejs/public/script.js#L28


                    scopes.push(checks[x].getAttribute('name'));
                }
            }
        }
    }

    var url = 'https://id.twitch.tv/oauth2/authorize'
        + '?client_id=' + client_id
        + '&redirect_uri=' + redirect_uri
        + '&response_type=code'
        + '&force_verify=' + force_verify
        + '&state=' + state
        + '&scope=';

    url += scopes.join('+');

    document.getElementById('auth_url_preview').textContent = url;
    document.getElementById('auth_url').setAttribute('href', url);
}
generate();

You just add force_verify=true to the URL you redirect the user to Twitch with

So

https://id.twitch.tv/oauth2/authorize?client_id=MyClientID&redirect_uri=MyRredict&response_type=code&scope=SCOPES

becomes

https://id.twitch.tv/oauth2/authorize?client_id=MyClientID&redirect_uri=MyRredict&response_type=code&force_verify=true&scope=SCOPES

It’s not beautiful nor recommandable (I think) but I found to way to easily do it with the sample. Simply add to the parameter authorizationURL “…?force_verify=true&” (https://id.twitch.tv/oauth2/authorize?force_verify=true&) and it worked for me. Thanks for your input, didn’t thought of this before.
