  1. Click the Login button in the upper, right.
  2. In the dialog, click the Log in with your Microsoft account button.
  3. This will show a second dialog where you can enter your credentials for your Xbox Live test account.

If you encounter this error message There was an error logging you in: Content isolation not authorized. make sure you are not logged into Mixer in another tab or browser with a non-sandbox account. The easiest way to get around this is to open an in-private browser session.
