Using Login Feature on different PCs about streamlink-twitch-gui

[bastimeyer]

It's because twitch deletes the OAuth token of your old login as soon as you login on a different machine, so the old session "expires".
There's not much I can do, that's simply how the oauth system works... 😕

If this is super annoying for you, you could copy over the oauth token of the logged in machine to the second one.
Start the application with the --remote-debugging-port=8888 parameter and open http://localhost:8888 in your browser. Then run the following line to read your access token:

JSON.parse( localStorage.getItem( "app" ) ).auth.records[1].access_token

On the other machine, do the same and run the following line to set the access token:

var access_token = "YOUR ACCESS TOKEN";
var obj = JSON.parse( localStorage.getItem( "app" ) );
obj.auth.records[1].access_token = access_token;
localStorage.setItem( "app", JSON.stringify( obj ) );

Then restart the app, so it can do the auto-login procedure...
