Discord Sign In
When choosing to sign in with Discord you will open a tab that asks you if you want to authenticate your sign in with your Discord app and also at the same time launches your Discord app if it is closed.
Inside your Discord app the Quest Portal Assistant will ask for you to authorise it to access your Discord account, the username, avatar and banner as well as your email address.
Once you authorise it asks you to return to your browser to finish setting up the connection.
